Review of the Congruence between Cytopathological and Histopathological Diagnoses of Archive Cases 2009-2016 from Department of Veterinary Pathology Zagreb
Citološka pretraga se rutinski primjenjuje u kliničkom radu radi svoje učinkovitosti, brzine i jednostavnosti. Patohistološka pretraga je složenija, zahtijeva više vremena za pripremu preparata, ali je ona zlatni standard za analiziranje arhitekture tkiva. Obje metode se provode na Zavodu za veterinarsku patologiju, no do sada nije ispitivana razina njihove podudarnosti za istovjetne lezije. Pretragom arhive Zavoda za veterinarsku patologiju, pronađeni su svi slučajevi (parovi) citoloških i histoloških pretraga od istovjetnih lezija u razdoblju od 2009. – 2016. godine. Obavljena je statistička analiza ispravnosti i korisnosti citoloških slučajeva u odnosu na histološke. Ne uključujući nedostatne slučajeve (20,7%), 80,4% slučajeva pokazuje potpunu ili djelomičnu podudarnost, a 19,6% nepodudarnost. Većina uzoraka je bila upravo iz područja kože (50,6%), te je u tom području 20,5% dijagnoza činio mastocitom, dok su ostale dijagnoze činile 79,5%. Rezultati su pokazali 96,6% podudarnosti za mastocitom, neovisno o sustavu. Ovakvi rezultati su podjednaki onim dobivenima u sličnim istraživanjima, bilo u humanoj ili veterinarskoj medicini. Predmetno istraživanje je pokazalo visoku razinu podudarnosti između citopatoloških i histopatoloških dijagnoza te je dokazalo da je citopatološka pretraga, koja se nadopunjuje s histopatološkom pretragom, vrlo važna i korisna inicijalna i orijentacijska pretraga u klasificiranju kožnih lezija domaćih životinja.Cytological examination is routinely applied in clinical work because of its efficiency, speed and simplicity. Histological examination is more complex, it requires more time for specimen preparation, but it is the gold standard for analyzing tissue architecture. Both methods are performed by the Department of Veterinary Pathology Veterinary Faculty, University of Zagreb, but the rate of congruency between those methods has not yet been investigated. The Department archives were searched for all cases (pairs) that went through both cytological and histological examination of the same lesion, between 2009 and 2016. Altogether 251 cases were found and the majority were canine. Statistical analysis of accuracy and efficiency of cytological cases in relation to histological cases was conducted on 251 cases registered in the Department archives between January the 1st 2009 and January the 1st 2016. With indecisive (non-diagnostic) cases excluded (20,7%), the rate of complete or partial congruency between cytological and histological diagnosis was 80,4%, and the rate of non-congruency was 19,6%. Majority of samples were taken from the skin region (50,6%), where mastocytoma had the rate of 20,5%, as opposed to other lesions which combined had a rate of 79,5%. Results have shown 96,6% congruency in mastocytoma cases, regardless of the region. The results are similar to those obtained in comparable researches, either human or veterinary medicine. Research concerned has shown a great congruency rate between cytological and histological diagnosis and cytological examination was proven (complemented with histological examination) as very important and useful screening method in classification of skin lesions in domestic animals
Trace analysis of persistent organochlorine compounds in soil and atmospheric particles
Razrađeni su postupci mikrovalne ili ultrazvučne ekstrakcije za multirezidualnu analizu tragova organoklorovih (OC) pesticida i specifičnih kongenera polikloriranih bifenila u tlu (35 spojeva) i u frakciji lebdećih čestica PM2,5 u zraku (27 spojeva). Otapalo za ekstrakciju bila je smjesa (n-heksan, aceton)=1:1. Pročišćeni ekstrakti analizirani su plinskom kromatografijom uz detekciju spojeva detektorom zahvata elektrona i spektrometrijom masa. Istražen je utjecaj sastojaka matrice tla na djelotvornost dvaju različitih postupaka ekstrakcije i selektivnost i osjetljivost odziva detektora. Mikrovalna ekstrakcija primijenjena je za analizu OC spojeva u tlima i jezerskim sedimentima skupljenim na području Nacionalnog parka Plitvička jezera te tlima skupljenim na području grada Varaždina, a ultrazvučna za analizu istih zagađivala u lebdećim česticama PM2,5 skupljenim u Zagrebu. Maseni udjeli OC zagađivala u tlu i sedimentima (ng kg-1 do g kg-1) kao i njihove masene koncentracije u česticama u zraku (pg m3) bili su na razini globalnog onečišćenja okoliša. U uzorcima tla i sedimenata najčešće je detektiran p,p'-DDE, a u česticama PM2,5 u zraku -heksaklorcikloheksan. Omjeri p,p'-DDE/p,p'-DDT u varaždinskim tlima i u lebdećim česticama u zraku upućuju na stalni unos tragova p,p'-DDT-a u okoliš. Masene koncentracije OC zagađivala u česticama PM2,5 u zraku bile su 2010. godine znatno niže od onih izmjerenih na istoj lokaciji u razdoblju od 2000. do 2003. godine.Abstract Microwave-assisted or ultrasound-assisted extraction procedures were developed for multiresidue trace analysis of organochlorine (OC) pesticides and specific polychlorinated biphenyl congeners in soil (35 compounds) and atmospheric particles PM2.5 (27 compounds). The extraction solvent was the mixture (n-hexane, acetone)=1:1. Purified extracts were analysed using gas chromatography with electron capture and mass spectrometric detection. The influence of soil matrix components on the efficiency of two different extraction procedures and on the selectivity and sensitivity of detector response was investigated. The microwave-assisted extraction was applied for the analysis of OC compounds in soils and lake sediments collected in the area of Plitvice Lakes National Park and in soils collected in the city of Varaždin, while the ultrasonic extraction was used for analyses of these pollutants in PM2.5 atmospheric particles collected in Zagreb. Mass fractions of OC pollutants in soils and sediments (ng kg-1 to g kg-1) as well as their mass concentrations in particles in air (pg m3) were at levels of global environmental pollution. The most frequently detected OC pollutant in soils and sediments was p,p'-DDE, and in PM2,5 particles in air -hexachlorocyclohexane. The p,p-DDE/p,p-DDT in Varaždin soils and in atmospheric particles indicated a constant input of p,p-DDT traces in the environment. Mass concentrations of OC pollutants in PM2.5 particles in air were considerably lower in 2010 than those measured at the same location in the 2000 to 2003 period
Vladimir Kirin's Illustrations in "Croatian Tales of Long Ago"
Prema mišljenju Ivane Brlić-Mažuranić, samo su dvojica ilustratora uspješno interpretirala njezina književna djela: slavni češki crtač Josef Lada koji je ilustrirao njezin dječji roman Čudnovate zgode šegrta Hlapića i Vladimir Kirin koji je, po općem priznanju čitateljske publike, izvrsno ilustrirao englesko izdanje „Priča iz davnine“. Vladimir Kirin jedini je ilustrator koji je u više navrata likovno opremio djela Ivane Brlić-Mažuranić. Ovaj rad istražit će povijest suradnje dvoje umjetnika, Ivane Brlić-Mažuranić i Vladimira Kirina. Štoviše, Kirinov rad na ilustriranju djela Ivane Brlić-Mažuranić nastavio se i nakon smrti književnice. Upravo na taj dio Kirinova rada, nakon 1938. godine, obratiti će se naročita pažnja jer je umjetnik očito izgubio onu moć uživljavanja u pripovjedni svijet Ivane Brlić-Mažuranić koja ga je tako nadahnjivala u ilustracijama za englesko izdanje. Također, istražit će se upotreba Kirinovih ilustracija u novijim izdanjima „Priča iz davnine“.According to Ivana Brlić-Mažuranić, only two illustrators have successfully interpreted her literary work: famous Czech drawer Josef Lada who illustrated her children's novel “Lapitch the Little Shoemaker” and Vladimir Kirin who, by general recognition of the reading audience, did a great job at illustrating English edition of “Croatian Tales of Long Ago”. Vladimir Kirin is the only illustrator who not only illustrated few of Ivana Brlić - Mažuranić's works but did it more than once. This paper will explore history of cooperation between two artists, Ivana Brlić- Mažuranić and Vladimir Kirin. What is more, Kirin's work on illustrating Ivana Brlić-Mažuranić's opus continued even after her death. Particular attention will be paid to that exact period of Kirin's work, after 1938, because artist clearly lost that power of giving himself into narrative world of Ivana Brlić-Mažuranić which inspired him so much in illustrations for English edition. Usage of Kirin's illustrations in newer editions of “Croatian Tales of Long Ago” will be explored as well
