Effects of Hypertonic Saline Solution on Clinical Parameters, Serum Electrolytes and Plasma Volume in the Treatment of Haemorrhagic Septicaemia in Buffaloes

This study was conducted to determine the efficacy of hypertonic saline solution (HSS) along with antibiotic (ceftiofur HCl) and non-steroidal anti-inflammatory drug (ketoprofen) in the treatment of haemorrhagic septicaemia in buffaloes. For this purpose, 50 buffaloes suffering from haemorrhagic septicaemia were randomly divided in two equal groups A and B. Group A served as control and was treated with ceftiofur HCl (IM) and ketoprofen (IV) @ 6 and 2 mg/Kg BW, respectively, for five days. Buffaloes of group B were administered with rapid intravenous infusion of hypertonic saline solution (7.5% NaCl) @ 4 ml/Kg BW once in combination with ceftiofur HCl and ketoprofen. Animals were monitored for 24 hours after initiation of treatment. Clinical parameters, serum electrolytes, plasma volume and survival index were recorded at different intervals after treatment. Survival rate (80%) in group B was significantly higher (P<0.05) than 48% in group A. The heart rate and respiration rate recovered more effectively in the buffaloes administered with treatment protocol B. Plasma volume was 98% which was almost normal within 24 hours after the infusion of hypertonic saline solution to the animals of group B. It was concluded from the study that hypertonic saline solution as an adjunct to antibiotic and a non-steroidal anti-inflammatory drug more efficiently improved respiration and heart rates and effectively restored plasma volume in resuscitating the buffaloes from haemorrhagic septicaemia than the conventional treatment

Congenital prepubic sinus: An aborted dorsal urethral duplication or a cloacal remnant?

Background: Congenital Prepubic Sinus (CPS) is an uncommon urogenital anomaly characterized by a blind tract between the skin over the pubis to anterior of the urinary bladder, Urethra or umbilicus. We report four such cases to emphasize varied clinical presentation and embryological conundrum. Methods: Following Ethical Review Committee (ERC) approval, medical records of pediatric patients (\u3c16 \u3eyears) presenting with CPS (identified through operating room records and Hospital Information Management System (HIMS) between 1994 and 2018 were reviewed for demographics, clinical presentation, investigations including histopathology, management and outcome. Results: Four cases of CPS, 3 females and 1 male, age range 9 months to 13 years were managed over 25-years. Clinical presentation includes a discharging sinus and recurrent episodes of cellulitis and abscess formation in pubic area and labia majora. Urological investigations were mostly normal. Insertion of lacrimal probe or plastic sheath of intravenous cannula through the sinus opening was useful to determine the course of sinus and aid its excision. Histology of excised sinus highlights the possible embryological origin. Concluions: CPS is a rare anomaly with varied clinical presentation. It seems CPS is an aborted urethral duplication (Stephen Type 3) or a Cloacal remnant. Complete excision of the tract in the reported cases was curative

Inhibition of protein glycation and advanced glycation end products by ascorbic acid

Advanced glycation end products (AGEs) formation is increased in diabetes mellitus, leading to microvascular and macrovascular complications. Recently, much attention has been focused on natural and synthetic inhibitors to delay the onset or progression of diabetes and its comorbidities. Ascorbic acid (AA) can react with proteins, including hemoglobin and possibly interfere with protein glycation process. An in vitro glycation model containing plasma from type 2 diabetic and non-diabetic healthy volunteers together with glucose as glycating agent was used to study antiglycation activity of AA. Samples with different concentrations of glucose and AA were incubated for five weeks at 37°C. Nonenzymatic glycation (NEG) was quantitated by thiobarbituric acid calorimetry and AGEs were measured by enzyme linked immuno-sorbent assay (ELISA). The NEG and AGEs levels were reduced by AA. Increasing the AA concentrations greatly diminished protein glycations, indicating dose-dependent effects of AA. Plasma NEG and AGEs were decreased with an average of 20 to 26% (p &lt; 0.05) and 26 to 28% (p &lt; 0.05). A significant correlation was found between the glycation inhibition and the inhibition of AGE formation (p &lt; 0.05). The antiglycation role of AA is evident in the present study and it also indicates the possibility of inexpensive, relatively non-toxic vitamin therapy for the prevention and treatment of diabetic complications. It is plausible that AGEs inhibition by AA may also form the basis for future intervention strategies in both diabetic and non-diabetic individuals.Keywords: Diabetes mellitus, glycation, advanced glycation end products, hyperglycemia, ascorbic aci

Effect of natural and synthetic fruit coatings on the postharvest quality of kinnow mandarins

Natural products are more preferred by consumers now-a-days over the synthetic ones. Therefore a natural fruit coating was developed from natural ingredients (shellac, rosin, gum arabic, water and ethanol from sugar industry) without ammonia or morpholine as an alternative to the synthetic coatings. So this research was devised to compare the effects of this newly developed natural fruit coating (with 9% total solids) with those of synthetic one (polyethylene based ammonia containing wax with 21% total solids) on the postharvest quality of kinnow (Citrus reticulata Blanco) mandarins. The kinnow mandarins were either coated with natural or synthetic fruit coatings or were left uncoated and stored at 5±2°C with 85-90% relative humidity for 63 days with five replications for each treatment. The results showed that both fruit coatings significantly (p0.05) changes in total soluble solids and fruit acidity were recorded for all the treatments. Furthermore the difference between natural and synthetic fruit coatings was non-significant (p>0.05). Therefore, it could be suggested that the natural fruit coating is a good alternative of the synthetic fruit coating

DNA Barcoding: Amplification and sequence analysis of rbcl and matK genome regions in three divergent plant species

Background: DNA barcoding is a novel method of species identification based on nucleotide diversity of conserved sequences. The establishment and refining of plant DNA barcoding systems is more challenging due to high genetic diversity among different species. Therefore, targeting the conserved nuclear transcribed regions would be more reliable for plant scientists to reveal genetic diversity, species discrimination and phylogeny.Methods: In this study, we amplified and sequenced the chloroplast DNA regions (matk+rbcl) of Solanum nigrum, Euphorbia helioscopia and Dalbergia sissoo to study the functional annotation, homology modeling and sequence analysis to allow a more efficient utilization of these sequences among different plant species. These three species represent three families; Solanaceae, Euphorbiaceae and Fabaceae respectively. Biological sequence homology and divergence of amplified sequences was studied using Basic Local Alignment Tool (BLAST).Results: Both primers (matk+rbcl) showed good amplification in three species. The sequenced regions reveled conserved genome information for future identification of different medicinal plants belonging to these species. The amplified conserved barcodes revealed different levels of biological homology after sequence analysis. The results clearly showed that the use of these conserved DNA sequences as barcode primers would be an accurate way for species identification and discrimination.Conclusion: The amplification and sequencing of conserved genome regions identified a novel sequence of matK in native species of Solanum nigrum. The findings of the study would be applicable in medicinal industry to establish DNA based identification of different medicinal plant species to monitor adulteration

Polymorphic noncoding region of GNRH1 gene in male patients with impaired fertility

Impaired male fertility is a multifactorial pathological condition and genetic contribution is up to 20%. Gonadotropin Releasing Hormone 1 (GNRH1) is associated with maturation of spermatozoa. We aimed to study genetic sequence of GNRH1 gene in azoospermia males. We collected 50 clinically diagnosed infertile males after the informed consent. DNA was extracted and primers were designed to amplify the exonic and exon/intron boundaries of exon 1 and exon 2 region of GNRH1 gene. The amplicons were sequenced and analyzed using bioninformatic tools. We have identified sequence variations at c.1325-131del.A, c.1325+40 T&gt;G, c.1325+34T&gt;G, c.1325+124 Ins. A, c.1325+126 Ins. A, c.1325+181T&gt;G, c.1325+264 Ins.G and c.1325+269 Ins. A positions. Human Splicing Finder predicted that c.1325-131del.A, c.1325+34T&gt;G, c.1325+124 Ins. A, c.1325+264 Ins.G and c.1325+269 Ins. A have impact on the splicing while c.1325+40 T&gt;G, c.1325+126 Ins. A and c.1325+181T&gt;G have relation with the splicing. The c.1325+40 reported in literature as rs2709608 but has no association with the male infertility. The c.1325+181T&gt;G We could not find other variations in the literature therefore suggested to be novel. Our study suggests that intronic region of GNRH1 gene a highly variable in Pakistani infertile male patients and suggests to explore its correlation with the disease on a large scale

Comparative efficacy of different adjuvant containing inactivated vaccines against low-pathogenicity Avian Influenza H9N2 virus

Background: Outbreaks of low-pathogenic Avian Influenza virus H9N2 (AIV-H9N2) occurred in poultry industry in Pakistan in 1998 and caused serious economic losses. Since then, many of the AIV-H9N2 vaccines have been introduced to Pakistani market to control the virus, however, it is still circulating all over the country. Therefore, the purpose of the study was to prepare and evaluate different adjuvant containing vaccines using local isolate of AIV-H9N2 in broiler birds.Methods: Three vaccines; Alum precipitated (AP-AIV), Aluminum hydroxide gel (AH-AIV) and Oil based (OB-AIV) were prepared in the laboratory and injected into broiler birds at 7th and 14th day of age. There were four groups of birds including one control group. To evaluate the serological response of the birds to vaccines, serum antibody titers were measured using haemagglutination inhibition test (HI). Vaccinated and control birds were challenged with AIV-H9N2 and virus shedding was determined from trachea and cloacal swabs by HI.Results: Out of the three prepared OB-AIV with hydrophile lypophile balance (HLB) values 5.37, 8.01 and 9.01, the vaccine with HLB value of 8.01 was the most stable. Each of the adjuvant containing vaccine was effective in inducing high HI antibody titers. However, OB-AIV was found to be the most effective in inducing a significantly higher (P<0.05) HI titer as compared to that of AP-AIV and AH-AIV each. No significant difference was observed between the HI titers induced by AP-AIV and AH-AIV. All the vaccines also showed effective protection against AIV-H9N2 challenge in vaccinated birds.Conclusion: In conclusion, this study reports the successful preparation and evaluation of adjuvant containing inactivated AIV-H9N2 vaccines. OB-AIV formulation was found to be most effective to control the H9N2 virus infections in broiler birds.

Reporting of mycetoma cases from skin and soft tissue biopsies over a period of ten years: A single center report and literature review from Pakistan

Background: Mycetoma is an important neglected tropical disease associated with debilitation, disfigurement and death if not diagnosed and treated adequately. In Pakistan, mycetoma cases have frequently been diagnosed in histopathology and microbiology laboratories. However, there is scarcity of published data from this country. Therefore, the objectives of this study were to evaluate the frequency and type of mycetoma reported in skin and soft tissue biopsies from a single center over 10 years and review of published literature from Pakistan.Method: This descriptive observational retrospective study was conducted at the Aga Khan University Hospital laboratory, Karachi, Pakistan. Laboratory data from 2009-2018 of skin and soft tissue biopsies with positive findings of mycetoma were retrieved from hospital information system. The variables for statistical analysis were age and gender of patient, anatomical site of lesion, residence of patient (geographical location) in the country, etiologic agents of mycetoma and significant gross and microscopic histopathological findings. The data was entered, and descriptive epidemiologic assessment was carried out using MS excel 2013. Geographical information system was used for mapping the location. Literature review of mycetoma cases reported from Pakistan was done on PubMed, Google search and PakMediNet from 1980 till April 2019.Result: During ten years of study period, 89 skin and soft tissue biopsies were reported as mycetoma, majority were eumycetoma [n = 66/89 (74%)] followed by actinomycetoma [n = 23/89 (26%)]. Involvement of lower limb was predominantly observed [n = 74/89 (83%)] in which foot had significant contribution [n = 65/74 (88%)]. Only 18 specimens were submitted for microbiological assessment and six grew agents of mycetoma, with Madurella mycetomatis reported in only three. Well-formed granuloma formation was observed in only 26%[n = 23/89] of cases. Specific geographical location was not identified, and cases were reported from across the country. From Pakistan, only two original papers and 7 case reports were available in published literature.Conclusion: This single center study reports a handful of cases of mycetoma from Pakistan. We conclude that the index of suspicion should remain high among treating surgeons and physicians and clinical laboratories should improve their diagnostic capacity and skills. This will have a great impact on disease outcome and patient\u27s life

Efficacy of Azadirachta indica (Neem) leaf extract and hypertonic saline solution as intratesticular chemical sterilizing agents in dogs

A castração consiste na indução da esterilidade por meio físico, químico ou hormonal. A castração química é uma técnica eficiente e confiável, em contraste com outros procedimentos de esterilização, pois é menos dolorosa para os métodos físicos e econômicos para os métodos hormonais. Azadirachta indica (neem), é uma planta carismática, pois possui folhas anti-inflamatórias, antimicrobianas e antiandrogênicas. Para diminuir a crescente população humana no sul da Ásia, o óleo de nim e o extrato de folhas de nim têm sido efetivamente usados como agente contraceptivo. O principal determinante deste estudo atual foi avaliar o Neem como um agente esterilizante químico (necrótico ou apoptótico) em cães injetados intratesticularmente em comparação com uma solução salina hipertônica. O tamanho da largura testicular pré e pós-injeção e as amostras de sangue para os níveis séricos de testosterona foram colhidas em dias alternados. Os resultados obtidos revelaram alterações substanciais no tamanho da largura testicular, perfil histopatológico e nível sérico de testosterona. Observou-se uma leitura não significativa (P&gt; 0,05) da largura testicular da pré-injeção, em contraste com um aumento significativo (P &lt;0,05) três dias após a injeção em todos os grupos competitivos. Os valores médios registrados para o tamanho da largura testicular no final do estudo via extrato de folhas de nim, HSS a 30% e grupos controle foram 27,7362 ± 2,3315 mm, 30,9594 ± 4,6861 mm e 24,5023 ± 2,5387 mm, respectivamente. Uma tendência decrescente, com relação ao nível sérico de testosterona sendo estatisticamente significante (P &lt;0,05), foi registrada nos grupos tratados (A, B), em contraste com o grupo controle (C), pois os valores eram 1,5357 ± 0,7819ng, 1,2669 ± 0,9095ng e 2,4517 ± 0,1827ng nos grupos A, B e C, respectivamente. Os achados histopatológicos advogaram a presença de corpos apoptóticos no grupo tratado com nim, enquanto a presença de células intersticiais degeneradas, túbulos seminíferos necrosados, epitélio germinativo danificado e espermatogênese interrompida também foi estudada nos dois grupos competitivos. Assim, o efeito apoptótico e a propriedade anti-inflamatória do extrato de folhas de nim resultaram em uma castração menos dolorosa e confirmaram que a Azadirachta indica foi um melhor substituto para a castração química do que a solução salina hipertônica.Castration refers to induced sterility via physical, chemical, or hormonal methods. Chemical castration is an efficient and reliable technique in contrast to other sterilization procedures as it is less painful to physical methods and cost‑effective to hormonal methods. Azadirachta indica (neem), is a charismatic plant as its leaves possess anti-inflammatory, anti‑microbial, and anti-androgenic chattels. To abate the escalating human population in South Asia, neem oil and neem leaf extract have been effectively used as a contraceptive agent. The key determinant of the current study was to evaluate Neem as a chemical sterilizing agent, (either necrotic or apoptotic), in dogs injected intratesticular in comparison to a hypertonic saline solution. Pre- and post-injection testicular width size and blood samples for serum testosterone levels were collected on alternative days. Results disclosed substantial changes in testicular width size, histopathological profile, and serum testosterone level. A non-significant (P &gt; 0.05) pre-injection testicular width readings in contrast to a significant increase (P &lt; 0.05) three days post-injection was noted in all the competitive groups. The mean values recorded for testicular width size at the end of the trial study via neem leaf extract, 30% HSS and, control groups were 27.7362 ± 2.3315mm, 30.9594 ± 4.6861mm, and 24.5023 ± 2.5387mm, respectively. A declining trend, regarding serum testosterone level being statistically significant (P &lt; 0.05) was recorded in treated groups (A, B) in contrast to the control group (C) as the values were 1.5357 ± 0.7819ng, 1.2669 ± 0.9095ng, and 2.4517 ± 0.1827ng in groups A, B, and C, respectively. Histopathological findings advocated the presence of apoptotic bodies in the neem treated group whereas the presence of degenerated interstitial cells, necrosed seminiferous tubules, damaged germinal epithelium, and ceased spermatogenesis was also studied in both competitive groups. Thus, the apoptotic effect and anti-inflammatory property of neem leaf extract resulted in less painful castration and verified Azadirachta indica as a better substitute for chemical castration in contrast to hypertonic saline solution
