The population density and breeding of two frog species, i. e., the Skittering Frog （Euphlyctis eyanophlyctis） and the Bull Frog （Hoplobatrachus tigerinus） were studied at Rawal Lake, Islamabad, Pakistan, by using visual encounter method from September 2009 to August 2010. Mean population density for the two frogs was 1.55 ± 0.44 frogs per ha, with that for the Skittering Frog being 1.09 ± 0.33 frogs/ha and that of the Bull Frog 0.46 ± 0.11 frog/ha, respectively. It is concluded that both frog species are explosive breeders, i. e., their breeding activities were confined to the first showers of the monsoon season. The mean spawn weight of the Skittering Frog was 1.5 g with more than 1000 eggs in each spawn, while that of the Bull Frog was 0.26 g with less than 1000 eggs in a spawn. The spawning sites of the two species were investigated in detail. Generally, no threat to their populations was observed. However, the opening of the spillway of Rawal Dam following the torrential rain destroyed the breeding sites of the frogs. It is maintained that the event did not produce any significant impact on their populations and breeding as the two species were quite common.

Background: This study was designed to investigate the BMI and alcohol consumption effects on hepatic enzymes. The degree of alteration among moderate drinkers is still unclear. Objective: To determine causes of liver failure due to alcohol and obesity. We observed the association between moderate alcohol consumption, body mass index (BMI;in kg/m2) and transaminase, cholestatic enzymes. Design: Serum alanine aminotransferase (ALT), alkaline phosphate (ALP), aspartate aminotransferase (AST), and gammaglutamyltransferase (GGT) were examined in 995 healthy persons. In this study 400 persons were reported as abstainers and 595 participants involved as a moderate drinkers. The study population was further split into according to BMI as follows: <19 (underweight), ≥19 and <25 (normal weight), ≥25 and <30 (over- weight), and ≥30 (obese). Results: Serum ALT (P < 0.002), GGT (P < 0.001) and ALP (P < 0.001) but not AST (P < 0.883) activities in moderate drinkers were higher than those in abstainers. Mean ALT activity is higher in obese and over weight in alcohol consumers and abstainers as compared to mean AST activity in the same groups. ALP activity was increased with BMI in moderate drinkers. In abstainers activity of ALP shows weak relation in order to BMI. Conclusion: The result of moderate alcohol use raises activity of hepatic enzymes with increasing BMI. Most participants with alcohol consumption have an AST/ALT ratio above 1.
