Arterijska vaskularizacija amigdale psa

We investigated the vascularization of the amygdala of the dog using various contrast agents injected into the internal carotid and vertebral artery. Subsequent clearance of the tissues gives us an opportunity to study the finest capillary network in the amygdala. The corticomedial part of the amygdala has a good vascularization given by the rostral and caudal choroid arteries. The rostral choroid gives off a rich capillary net to the nucleus centralis (NCE), its pars lateralis (NCEL) and pars medialis (NCEM). Nucleus medialis (NM) is poorly vascularized compared to the central nuclei. The massa intercalata (MI) also has a delicate artery around which there is a fine net of capillaries. Nucleus corticalis (NCO) and area enthorhinalis (AER) are better vascularized by the subpial blood vessel. The caudal choroid, a branch of the caudal cerebral artery is a source of subpial capillaries. The basolateral part of the amygdala is very well vascularized by the rostral choroid artery, a branch of the middle cerebral, especially the nucleus basolateralis (NBL) and nucleus lateralis posterior (NLP). The nucleus basomedialis (NBM) is poorly vascularize by the rostral choroid artery . The amygdala, is served by the middle cerebral artery, via its branch, the rostral choroid, and the caudal cerebral artery via its branch the caudal choroid artery. Every amygdala nucleus has its own central artery around which is formed a rich net of capillaries.Proučavanje vaskularizacije amigdale psa vršeno je upotrebom različitih kontrasnih sredstava injiciranih u a. carotis interna i a. vertebralis a prosvetljavanje tkiva daje mogućnost da se prouči i najfinija vaskularna mreža u amigdali. Kortikomedijalni deo amigdale vaskularišu a. choroidea rostralis i a. choroidea caudalis. A. choroidea rostralis, daje bogatu mrežu kapilara u NCE (nucleus centralis) i njegovom lateralnom i medijalnom delu (NCEL i NCEM). Nucleus medialis (NME) je slabije vaskularisan u poredjenju sa vaskularizacijom NCE. Massa intercalata (MI) je takodje snabdevena bogatom mrežom kapilara. A. choroidea caudalis, kao subpialna arterija, vaskulariše NCO (nucleus corticalis) i AER (area enthorhinalis). Bazolateralni deo amigdale vaskulariše samo a. choroid rostralis. Bogata mreža kapilara uočava se u NBL (nucleus basolateralis) i NLP (nucleus lateralis posterior) a nešto siromašnija u NBM (nucleus basomedialis). Krv u amigdalu dovode dve arterije: a. choroidea rostralis, grana od a. cerebri media, i a. choroidea caudalis, grana od a. cerebri caudalis. Svaki nukleus amigdale ima svoju centralnu arteriju i oko nje jako razvijenu mrežu kapilara

Arterijska vaskularizacija mozga malog zelenog majmuna, Cercopithecus aethiops sabeus

Cell cultures from the small green monkey are used for the cultivation of poliovirus in the manufacture of vaccines against poliomyelitis. In addition kidney cultures from the same monkey serve for detection of the virus in biological material. This was the main reason that prompted us to undertake a study of one part of the monkey’s cardiosvascular system and thus contribute to a better understanding of the structure of its body.Glavni krvni sudovi koji dovode arterijsku krv u mozak su A.carotis interna i A. vertebralis. Spajanjem leve i desne kičmene arterije (A. vertebralis sinistra et dextra) nastaje A. basilaris cerebri. A. carotis interna sinistra et dextra pružaju se kroz parafaringealni prostor prema lobanjskoj duplji, u koju ulaze pošto prođu kroz karotidne kanale (canales carotici) piramide slepoočne kosti u kavernozni sinus u kome se povezuju obe Aa. carotides preko A. intercarotica caudalis. Grane A. carotis internae su: A. ophthalmica, A. cerebri media, A. communicans caudalis. A.ophthalmica dovodi krv u optičke i pomoćne delove oka. A. cerebri media daje grane koje ulaze u moždanu masu i dovodi krv u lateralnu površinu moždane hemisfere. A. communicans caudalis povezuje zadnju moždanu arteriju (A. cerebri caudalis) sa unutrašnjom karotidnom arterijom i daje grane za vaskularizaciju hipotalamusa. A.cerebri rostralis je produžetak stabla unutrašnje karotidne arterije. Ona se spaja sa odgovarajućom granom druge strane ispred Chiasma opticum. Iz ovog spoja nastaje A. cerebri rostralis communis. Od A. cerebri rostralis odvajaju se površne i duboke grane koje ulaze u moždanu masu. A. cerebri caudalis, A. communicans caudalis i A. cerebri rostralis obrazuju oko hipofize i raskršća vidnih nerava arterijski krug (Circulus arteriosus Willisi)

Efekti estrogena i luteinizirajućeg - oslobađajućeg hormona na hromatin u CA3 regionu hipokampusa mužjaka pacova

The structure of heterochromatin protects genome from undesirable recombinations, while estrogen and luteinizing-releasing hormone (LHRH) cause changes in structure of chromatin. The objective of this study was to prove the connection of neonatally applied estro­gen and LHRH, with shown effects on chromatin in hippocampus of adult male rats. Stereological results have shown that total surface of neuron area in estrogen treated animals significantly reduced in regard to the control group as well as groups treated with LHRH. The number of heterochromatin granules in either estrogen or LHRH treated groups significantly increased, while in the last fourth group treated with both estrogen and LHRH the difference is even more expressed, both in regard to the control group and oth­er groups.Struktura heterohromatina štiti genom od neželjenih rekombinacija, dok estrogen i luteinizirajući-oslobađajući hormon (LHRH) uzrokuju promene u samoj strukturi hromatina. Studija je napravljena sa ciljem dokazivanja povezanosti neonatalno aplikovanog estrogena i LHRH, sa ispoljenim efektima na hromatinu u hipokampusu odraslih mužjaka pacova. Stereološki rezultati su pokazali da je ukupna površina neurona kod životinja tretiranih estrogenom značajno smanjena u odnosu na kontrolnu i grupe tretirane LHRH. Broj granula heterohromatina u grupama tretiranim estrogenom i LHRH je primetno povećan, dok je u poslednjoj, četvrtoj grupi tretiranoj i estrogenom i LHRH ova razlika još izraženija, kako u odnosu na kontrolnu, tako i u odnosu na ostale grupe

Influence of estradiol on neurons of nucleus basomedialis in the amygdaloid complex of female rats

The amygdaloid complex (AC) of rat brain is sensitive to sex steroids, especially during neonatal development. The aim of this investigation was to determine possible changes in neuron morphology of the basomedial nucleus (BMN) of the AC in female rats treated with estradiol. Two straining techniques were used: (1) standard histological staining with hematoxylin-eosin and (2) the Golgi method. Three types of neurons: pyramidal, fusiform and stellate were subjected to stereologic analaysis. Estradiol significantly increased the volume of neuronal soma of all three neuronal types at 16 and 90 days of age, whereas at day 38 changes were observed only in fusiform and stellate neurons. In addition, the volume of cell nuclei was increased but the number of neurons per unit area decreased at all experimental intervals examined. Therefore, estradiol causes stereologically detectable changes in the size and number of neurons in BMN AC

Influence of human chorionic gonadotropin (hcg) on the neurons of nucleus medialis of rat amygdala repetedly treated in mature period of life

Humani horiogonadotropin (hCG) pripada familiji glikoproteinskih hormona, molekularne mase 38 kD /Mr/. S obzirom na to da su naša ranija proučavanja pokazala da su neuroni oba filogenetska dela amigdale (AMY), corticomedialis (CM) i basolateralis (BL), osetljivi na egzogeno uneti hCG, u sadašnjem istraživanju, primenom morfometrijskih analiza, želeli smo da utvrdimo da li i kako hCG deluje na neurone medijalnog amigdaloidnog nukleusa (NM AMY). Ženke pacova tretirane su jednom dozom 5 IU hCG, višekratno, u vreme polne zrelosti, od 46. do 68. dana života, a žrtvovane su u etarskoj narkozi 69. dana starosti. Mozak je izolovan, fiksiran u Bouin soluciji i ukalupljen u parafin. Preparati su serijski sečeni sa debljinom reza od 5 µm i obojeni H&E, po Bodianu i Biaschowskom. Morfometrijskom analizom, uz upotrebu Waibel-ovog mnogonamenskog testnog sistema, ispitivan je volumen jedara neurona (V) NM AMY i broj neurona na jedinicu površine (NA). Statistička značajnost je određivana primenom Studentovog t-testa. Morfometrijska analiza volumena jedara neurona (V) NM AMY kontrolne grupe ženki pacova žrtvovanih 69. dana starosti pokazala je da volumen (V) iznosi 500,51 (µm3), a broj neurona na jedinicu površine (NA) 1095,5 (mm2). Kod ženki pacova koje su višekratno tretirane sa 5 IU hCG u periodu od 46. do 68. dana starosti, volumen jedara neurona iznosi 637,79 (µm3), a broj neurona na jedinicu površine (NA) 641,2 (mm2). Statističkom analizom ustanovili smo da postoji povećanje volumena jedara neurona NM AMY tretiranih ženki pacova (p<0.01) i statističko smanjenje broja neurona (NA) na jedinicu površine (p<0.01). Analiza rezultata ženki pacova višekratno tretiranih sa hCG, koje su žrtvovane 69. dana života, u polno zrelom periodu, pokazala je da hCG ispoljava efekat povećanja volumena jedara neurona (V) i smanjenja broja neurona na jedinicu površine (NA).Human chorionic gonadotropin (hCG) belongs to family of glycoprotein hormones with molecular mass of 38kD /Mr/. Considering that our earlier investigation showed that the neurons of both phylogenetical amygdala (AMY) parts, AMY corticomedialis and AMY basolateralis were sensitive of exogenous hCG, in the present investigation using morphometric analysis, we wanted to establish if and how, hCG is acting on neurons of medial amygdaloid nucleus. The female rats were treated with single dose of 5 IU hCG repeatedly from 46. to 68. day, in their mature period of life, and sacrificed in ether narcosis on the 69. day of life. The brains were isolated, fixed in Bouin solution and formed into paraffin. The preparations, 5 µm serial cutted, were stained with H&E, and method according to Bodian and Biaschowsky. Using morphometric analyses, with the Weibel multipurpose test system, we investigate the volume of neuronal nuclei /V/ NM AMY and the number of neurons (NA) per square unit (mm2). Statistical significance was tested with Student’s T-test. In the control female rats group (sacrificed on the 69. day of life), the morphometric analysis of V NM AMY showed that the V was 500,51 µm3 and the number of neurons (NA) 1009,5 mm2. In treated female rats group (repeatedly treated with 5 IU hCG from 46. to 68. day of life), the volume of neuronal nuclei was 637,79 µm3 and the number of neurons (NA) per square unit was 641,2 mm2. With statistical analysis in treated female rats we establish the increase in volume of neuronal nuclei of NM AMY (p<0.01) and statistical decrease (p<0.01) in number of neurons (NA). Analyzing the results of female rats repeatedly treated with hCG and sacrificed on 69. day of life (mature rats) showed, that hCG demonstrates the increase in volume neuronal nuclei /V/ and decrease in number of neurons (NA) per square unit.Zbornik kratkih sadržaj

Izučavanje proliferacije zrnastih ćelija girus dentatusa neonatalnih ženki pacova tretiranih polnim hormonima

This study was designed to determine whether adult neurogenesis occurs in the dentate gyrus of rats, and to explore the possibility that this process is regulated by the activation of sex hormones. The proliferation of hippocampal dentate gyrus granule cells was investigated using 80 nC; 3H thymidine incorporation in the first group andin the second grouph 80 μCi3H - thymidine and 1mg estrogene dipropionae. We proved the existence of a stronger proliferation of granule cells in SGZ GD in female rats. The third group of newborn female Wistar rats was treated at 4 and 8 a days of ageold with a single dose of 2 mg of testosterone propionate. We proved the existence of minor damages of granule cells in SGZ GD. In the fourth group treated at 15 days of age, a single dose of 4 mg testosterone propionate and sacrificed when 60 days old, we proved the existence of minor damages of granular cells in SGZ GD. Our results suggest a differential effect of sex hormones on dentate gyrus granule cells proliferation through early life in rats.Proliferacija zrnastih ćelija gyrus dentatus-a izučavana je ugrađivanjem 3H -timidina kod kontrolnih i estrogenom tretiranih pacova. Novorođene, tri dana stare ženke pacova Wistar soja, tretirane su jednom dozom od 1 mg estradiola i sa 80 u.Ci 3H-timidina, a žrtvovane su 38. dana. Izučavanjem gyrus dentatus-a hipokampusa ženki pacova tretiranih estrogenom ustanovljen je povećan broj obeleženih zrnastih ćelija u granularnom sloju. U infrapiramidalnom delu, povećanje broja obeleženih ćelija u tretiranih životinja, bilo je značajno u svim zonama granularnog sloja. U suprapiramidalnom delu granularnog sloja, značajan porast broja obeleženih ćelija je dokazan je samo u supragranularnoj (SGZ) i ekstragranularnoj zoni (EGZ). Naši rezultati ukazuju da postoji specifičan efekat estradiola na proliferaciju zrnastih ćelija gyrus dentatus-a tokom ranog razvoja kod pacova. Ustanovljeno je da ženke tretirane 4. i 8 dana života sa po 2 mg TP imaju manja oštećenja u subgranularnom sloju SGZ, u odnosu na ženke tretirane 15. dana života sa 4 mg TP u GD. Kod ženki pacova tretiranih sa dve doze TP 4. i 8. dana neonatalnog života nema većih oštećenja u SGZ GD kao sto je to slučaj kod ženki tretiranih 15. danakasnog neonatalnog života sa jednom velikom dozomTP u SGZ oba dela GD. U tom periodu je ustanovljen veliki broj degenerisanih glija ćelija i neurona u SGZ oba dela GD. Ovi rezultati navode na zaključak da postoje različiti efekti polnih hormona na gyrus dentatus granularnih ćelija čija se proliferacija odvija u neonatalnom periodu života pacova

The median artery in the molle rat ( Spalax leucodon )

У области експерименталне хумане и ветеринарске медицине, као и у другим научним дисциплинама, све се више придаје значај лабораторијским животињама. На њима се могу пратити функције одређених система и њихове фармакодинамске манифестације, које настају зависно од врсте, путева и начина уношења појединих супстанци или биолошких агенаса у организам ових животиња. Један од значајних услова за оваква испитивања представља потпуно познавање анатомске грађе организма ових животиња. То је био један од главних разлога, да обрадимо део кардиоваскуларног система слепог кучета и на тај начин дамо прилог бољем познавању грађе тела ове животињe. За испитивање употребљено је 20 слепих кучића. После искрвављења животиња, у крвне судове су убризгане различите контрастне масе, желатин обојен сликарском темпером или минијумом. Крвни судови су после тога препарисани и сликани. А. mediana представља наставак брахијалне артерије, која се пружа у подлакатни предео у коме се налази уз N. medianus и V. mediana. Покрива је M. flexor carpi radialis, M. pronator teres и M. flexor carpi ulnaris, а затим наставља своје пружање према дисталном делу екстремитета, тако да на воларној страни у пределу прста даје за сваки прст по један крвни суд. Од А. mediana дистално од лакатног зглоба одваја се А. profunda antebrachii, која васкуларише флексоре карпалног зглоба и флексоре прста. Једна од грана А. mediana-е је и А. radialis. То је танак крвни суд, који се пружа према карпалном зглобу, између Radius-a и M. flexor carpi radialis. А. mediana у слепог кучета, слично као код златног хрчка, пацова и текунице је продужетак од A. brachialis.The experimental human and veterinary medicines, as well as other scientific disciplines, are turning more and more to laboratory animals. These are suitable for monitoring the functions of certain systems and their pharmacodynamic manifestations, which occur depending on the species, route and manner of administration of certain substances or biological agents in the organisms of those animals. One of the important prerequisites for such investigations is a thorough knowledge of the anatomic structure of the given organism of such animals. This was one of the main reasons why we undertook to investigate the cardio-vascular system of the molle rat contributing in that way to a better understanding of the body structure of this animal. The investigation was performed on 20 molle rats. After bleeding out, various contrast agents were administered, such as gelatin stained with painting tempera or minium. After this the blood vessels were mounted and photographed. The median artery is the distal continuation of the brachial artery. It courses along the medial side of the antebrachial region, following the median nerve and median vena. It first passes between the flexor carpi radialis, pronator teres and flexor carpi radialis and than descendens to the volar side of the digitus where it gives off digital arteries to each of digits.The median artery, distally to the cubital joint , gives off the deep antebrachial artery wich supplies carpal and digital flexor muscles. The radial artery is the thin vessel which arises from the median, extends to the carpal joint, between the radius and M. flexor carpi radialis and supply that muscle. The median artery in the molle rat , similarly to the golden hamster, rat and ground squirrel is the continuation of the brachial artery.Zbornik kratkih sadržaj

The renal artery in the molle rat (Spalax leucodon)

U oblasti eksperimentalne humane i veterinarske medicine, kao i u drugim naučnim disciplinama, sve se više pridaje značaj laboratorijskim životinjama. Na njima se mogu pratiti funkcije određenih sistema i njihove farmakodinamske manifestacije, koje nastaju zavisno od vrste, puteva i načina unošenja pojedinih supstanci ili bioloških agenasa u organizam ovih životinja. Jedan od značajnih uslova za ovakva ispitivanja predstavlja potpuno poznavanje anatomske građe organizma ovih životinja. To je bio jedan od glavnih razloga, da obradimo deo kardio-vaskularnog sistema slepog kučeta i na taj način damo prilog boljem poznavanju građe tela ove životinje. Za ispitivanje upotrebljeno je 25 slepih kučića. Posle iskrvavljenja životinja, u krvne sudove su ubrizgane različite kontrasne mase, želatin obojen slikarskom temperom ili minijumom. Krvni sudovi su posle toga preparisani i slikani. A. renalis je paran krvni sud. Počinje iz trbušne aorte 3-4 mm kaudalno od A. mesenterica cranialis. Svaka ide prema bubregu svoje strane. Desna bubrežna arterija počinje nešto kranijalnije nego leva. A. renalis dextra je nešto duža od A. renalis sinistra. Ona ukršta V. cava caudalis na njenoj dorzalnoj strani. Pre ulaska u bubreg svaka bubrežna arterija se deli na Ramus dorsalis i Ramus ventralis. Od leve bubrežne arterije, u blizini njene deobe na Ramus dorsalis i Ramus ventralis, odvaja se jedna grana, koja se pruža u kranijalnom pravcu i ulazi u levu nadbubrežnu žlezdu u njenom kaudalnom kraju. Od desne bubrežne arterije, u blizini njenog ulaska u desni bubreg, odvaja se jedna grana za desnu nadbubrežnu žlezdu. Ona se pruža u kranijalnom pravcu i ulazi u desnu nadbubrežnu žlezdu na njenom kaudalnom kraju. Pre njenog ulaska u desnu nadbubrežnu žlezdu od nje se odvaja jedna grana, koja se pruža u kranijalnom pravcu prema dijafragmi i dovodi krv u dijafragmu (A. phrenica caudalis). Kod slepog kučeta A. renalis je paran krvni sud i počinje iz trbušne aorte. Desna bubrežna arterija počinje nešto kranijalnije od leve. Pre ulaska u bubreg svaka bubrežna arterija se deli na Ramus dorsalis i Ramus ventralis.The experimental human and veterinary medicines, as well as other scientific disciplines, are turning more and more to laboratory animals.

The investigation was performed on 25 molle rats. After bleeding out, various contrast agents were administered, such as gelatin stained with painting tempera or minium. After this the blood vessels were mounted and photographed. A. renalis is a paired vessel arising from abdominal aorta 3-4 mm caudally from A. mesenterica cranialis. Each of the two renal arteries courses towards kidney at its side. Right renal artery arises slightly more cranially than the left one. A. renalis dextra is also slightly longer than A. renalis sinistra. It crosses V. cava caudalis dorsally. Each renal artery divides into Ramus dorsalis and Ramus ventralis and then penetrates kidney as mentioned. From A. renalis sinistra, close to its division into Ramus dorsalis and Ramus ventralis, one branch emerges, runs cranially and enters left adrenal gland at its caudal end. From A. renalis dextra, close to its enter to right kidney, one branch for right adrenal gland arises. It courses cranially and enters right adrenal gland at its caudal end. Before its enter into right adrenal gland, out of it one branch arises, courses cranially towards diaphragm and supplies the diaphragm with blood (A. phrenica caudalis). In molle rat, A. renalis is a paired vessel arising from abdominal aorta. A. renalis dextra emerges slightly more cranially from the left one. Before its penetration into kidney each renal artery divides into Ramus dorsalis and Ramus ventralis.Zbornik radova i kratkih sadržaj

Arteria subclavia i njene grane u malog zelenog majmuna (Cercopithecus aethiops sabeus)

Within experimental, human and veterinary medicine, more and more attention has been paid to experimental animals. One of them being the small green monkey (Cercopithecus aethiops sabeus). The small green monkey (Cercopithecus aethiops sabeus) has a shod muzzle, small teeth, and is mostly of gray-greenish color; the lower pan of its neck, chest, belly and inner sides of its thoracic limbs being whitish. Its total length is about 110 cm, the tail being 50 cm long. On its head, on both sides, there are white hairs directed towards the neck, reminiscent of whiskers. The monkeys have large buccal sacs. The extremities and tail are more gray than the rest of the body. The skin of the face, ears and fore limbs is black. The digits are very long, whilst the thumb short. Cell cultures from the small green monkey are used for the cultivation of poliovirus in the manufacture of vaccines against poliomyelitis. In addition, kidney cultures from the same monkey serve for detection of the virus in biological material. This was the main reason that prompted us to undertake a study of one part of the monkey's cardiosvascular system and thus contribute to a better understanding of the structure of its body.A. subclavia sinistra malog zelenog majmuna se direktno odvaja od luka aorte a A. subclavia dextra se odvaja od Truncus brachiocephalicus-a zajedničkim stablom sa A carotis communis dextra. A. subclavia sinistra et dextra su krvni sudovi koji vaskularišu levi i desni prednji ekstremitet, prednji deo grudnog koša i kaudalni deo vrata. Od A. subclavia odvajaju se: A. vertebralis, A. scapularis dorsalis, A. thoracica interna, zajedničko stablo za A. cervicalis superficialis i A. suprascapularis i Truncus costocervicalis. A. vertebralis i A. carotis interna su glavni krvni sudovi koji dovode arterijsku krv u mozak. A. vertebralis daje grane za duboke vratne mišiće (ramimusculares), kao i grane za kičmenu moždinu (ramispinales). Spajanjem leve i desne kičmene arterije (A. vertebralis sinistra et dextra) nastaje A. basilaris cerebri. A, scapularis dorsalis daje grane za vaskularizaciju M. serratus ventralis i za mišiće i kožu grebena leđa. A. thoracica interna daje rami intercostales ventrales koji anastomoziraju sa završnim granama dorzalnih međurebarnih arterija (A. intercostales dorsales). Zajedničko stablo za A. cervicalis superficialis i A. suprascapularis se odvaja na istom mestu od A subclavia gde i A thoracica interna, ali se pruža na suprotnu stranu od A. thoracica interna. A. cervicalis superficialis daje grane za vaskularizaciju mišića vrata koji leže ventralno od dušnika i za limfne čvorove ovog dela vrata. A suprascapularis vaskulariše mišiće proksimalnog dela ramenjače. Truncus costocervicalis je zajedničko stablo za A. intercostalis suprema, A. cervicalis profunda i A. transversa scapulae
