Efectos de la Diabetes Inducida por STZ en los Pesos Relativos de Riñón, Hígado y Páncreas en Ratas Albinas: un Estudio Comparativo * Muhammad Zafar & ** Syed Naeem-ul-Hassan Naqvi ZAFAR, M. & NAEEM-UL-HASSAN NAQVI, S. Effects of STZ-Induced diabetes on the relative weights of kidney, liver and pancreas in albino rats: a comparative study. Int. J. Morphol., 28(1):135-142, 2010. SUMMARY:We studied the effects of streptozotocin (STZ)-induced diabetes on the body weights of animals and the relative weights of kidney, liver and pancreas in albino rats. The aim of the study was to find an association between the reduction in the body weights of diabetic animals and the relative weights of kidney, liver and pancreas in proportion to the body weight of animals in albino rats. This study was performed in the Surgeons (CPSP) Pakistan in 2007-08. Diabetes was induced by a single dose of STZ (45 mg/kg, b.w.) given intraperitoneally in sodium citrate buffer at pH 4.5. Eighty albino rats were divided into five groups: control (A) and STZ treated (B, C, D, and E) which were sacrificed 2, 4, 6 and 8 weeks post treatment respectively. All the animals were weighed prior to the administration of streptozotocin and at sacrificial time. Kidney, liver and pancreas were removed, dried and weighed on Sartorius balance. The body weights of animals in different groups changed at variable time intervals. The Kidney weight was significantly increased, liver weight was slightly increased while the weight of pancreas was unaffected when compared with the weight of diabetic animals. It seems that the STZ-induced diabetes causes a significant reduction in the body weight of diabetic animals while the relative weights of kidney and liver were increased and the weight of pancreas was unaffected.

ZAFAR, M.; NAEEM-UL-HASSAN NAQVI, S.; AHMED, M. & KAIMKHANI, Z. A. Altered liver morphology and enzymes in streptozotocin induced diabetic rats. Int. J. Morphol., 27(3):719-725, 2009. SUMMARY:This study was undertaken to evaluate the relationship and effects of diabetes on liver morphology, architecture and function. The hepatic effects of diabetes were evaluated in vivo using streptozotocin (STZ)-induced diabetic rats as an experimental model. The degree of hepatic dysfunction was measured by using biochemical parameters like serum transaminases (ALT and AST), alkaline phosphatase (ALP)and pseudocholinesterase (PChE) while the histopathological studies were carried out to support the enzymic Parameters. The aim of the study was to investigate the association between diabetic hepatic complications and liver enzyme alterations. This study was performed in the . Diabetes was induced by a single dose of STZ (45 mg/kg, b.w.) given intraperitoneally in sodium citrate buffer at pH 4.5. Eighty albino rats were divided into five groups: control (A) and STZ treated (B, C, D, and E) which were sacrificed 2, 4, 6 and 8 weeks post treatment respectively. Histopathological examination of liver showed accumulation of lipid droplets, lymphocytic infiltration, increased fibrous content, dilatation and congestion of portal vessels and proliferation of bile ducts. Increased levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), ALP and PChE were observed in the liver. It seems that the diabetic complications in the liver like hepatocyte destruction etc. are likely to be due to alterations in enzyme levels.

SUMMARY:We studied the effects of streptozotocin (STZ)-induced diabetes on kidney morphology, anatomy, architecture and on the activities of aminotransferases (AST and ALT), alkaline phosphatase (ALP) and pseudocholinesterase (PChE) in albino rats. The aim of the study was to investigate the association between diabetic kidney complications and kidney enzyme alterations. This study was performed in the Department of Anatomy and Institute of Pharmaceutical Sciences, Baqai Medical University, Karachi and Pathology department of College of Physicians & Surgeons (CPSP) Pakistan in 2007-08. Diabetes was induced by a single dose of STZ (45 mg/kg, b.w.) given intraperitoneally in sodium citrate buffer at pH 4.5. Eighty (80) albino rats were divided into five groups: control (A) and STZ treated (B, C, D, and E) which were sacrificed 2, 4, 6 and 8 weeks post treatment respectively. Histopathology of kidney showed lesions similar to human glomerulosclerosis, glomerular membrane thickening, arteriolar hyalinization and tubular necrosis. Increased levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and pseudocholinesterase (PChE) were observed in the kidney. It seems that the diabetic complications in the kidney are likely to be associated with alterations in enzyme levels.

Background: Premature Rupture of Membranes (PROM) is common in obstetrics and management of such patients depends on whether the rupture has occurred or not. With membranes ruptured the fetus is deprived of protection provided within the amniotic cavity. Beta-Human chorionic gonadotrophin (β-HCG) is a hormone and is present in high concentration in amniotic fluid as well as in the blood and urine of the mother and is studied as possible predictor of preterm labour and as marker of PROM. Objective: To compare the diagnostic accuracy of B-hCG & nitrazine paper test in vaginal washings taking amniotic fluid pooling as gold standard for diagnosing premature rupture of membranes. Material & Methods: It was a comparative cross-sectional study conducted at Unit Department, of Obstetrics & Gynecology, Lahore General Hospital, Lahore. After that vaginal washings were taken for β-hCG testing. A pregnancy test kit (Accu Check) was used for detection of β-hCG in vaginal fluid washings. According to amount of µ-hCG in the washings the result has been positive as early as 40 Seconds but for labeling the result negative 5 minutes complete reaction time has been observed. On netrizine kit, the positive test is indicated by distinct colour band on both; control and test side. Results: Mean age of women was 27.17+4.55 years. Mean age of gestation was 36.16 + 3.30 weeks. Sensitivity & specificity of Nitrazine Paper Test were 92.17% & 66.67%. However the PPV & NPV for Nitrazine Paper Test was 98.15% & 30.77% respectively. Sensitivity & specificity of β-hCG Test was 94.35% & 75%. However the PPV & NPV for β-hCG test was 98.64% & 40.91% respectively. Conclusion: Results of this stud y showed that B-subunit of hCG measured by over-the-counter available pregnancy test kit is a dependable quick and easy test for detection of premature rupture of membranes. This test can be performed on the bed side of the patient without Lab involvement. This test can be promoted as an additional help for the diagnosis of doubtful and ambiguous cases of premature rupture of membranes.

Objectives: To compare the efficacy of Metformin with insulin in gestationaldiabetes mellitus in terms of fetomaternal outcome. Study Deign: Randomized clinicaltrial study. Setting: Lady Aitchison Hospital Lahore. Period: January 2014 to March 2015.Methodology: Total 500 pregnant females with GDM were included in the study through nonprobability,consecutive sampling. Patients were divided into 2 equal groups (A: B). Patientsin group A were given tablet metformin 500 mg by oral route and group B was administratedregular injection Insulin by subcutaneous route. Results: The mean age of females was32.14±6.13 years. The mean gestational age was 31.07±3.8 weeks. There were 78 (15.6%)females who had 0 parity, 107 (21.4%) females had parity 1, 175 (35%) females had parity2, 95 (19%) females had parity 3, 33 (6.6%) females had parity 4 and 12 (2.4%) femaleshad parity 5.There were 54 (10.8%) cases had PTB, out of which 12 (4.8%) had PTB withmetformin while 42 (16.8%) had PTB with insulin. There were 115 (23%) neonates requiredNICU admission, out of which 37 (14.8%) neonates with metforminand78 (31.2%) neonateswith insulin. There were 87 (17%) neonates who had neonatal hypoglycemia, out of which23 (9.2%) neonates with metformin and64 (25.6%) neonates with insulin. The difference wassignificant between both groups for all fetal outcomes (P<0.05). Conclusion: The metforminis more effective in preventing adverse fetal and maternal outcome as compared to insulin.
