Plasma luteinizing hormone (LH), progesterone, testosterone, estradiol, and estrone of the male and female quail were determined by a radioimmunoassay. Progesterone and testosterone or progesterone and LH were determined continuously in ovulating or nonovulating female quail and male quail at 3 hr intervals throughout the day. In another set of experiments, plasma LH, progesterone, estradiol, and estrone were determined simultaneously in ovulating quail, which were autopsied at 3 hr intervals. The plasma progesterone concentration showed a peak 3 hr before ovulation and reached basal level at the time of ovulation, whereas no peak could be observed at any time in the nonovulating or male quail. The LH showed a peak 3 to 6 hr before ovulation and reached the minimum at the time of ovulation, whereas in males and nonovulating quail no specific trend could be observed. Plasma testosterone, estradiol, and estrone levels peaked at 6 hr before ovulation in ovulating quail, whereas testosterone in male and in nonovulating quail showed a peak at 1400 hr.
Objective: To compare the effect of smoking over lipid profile. Method: Total 100 subjects were included in this study, 50 were smoker and 50 non-smoker. All the factors other then smoking those can lead to dyslipidemia were ruled out. All patient's fasting blood sample was collected and lipid profile was estimated. Data was analysed and't' value was calculated. Results: Serum levels of total cholesterol (TC), triglycerides (TG), low density cholesterol (LDL), very low density cholesterol (VLDL) were found to be significantly high in smokers in comparison to non-smokers but high density cholesterol (HDL) did not any significant difference between two groups. Conclusion: Smoking affects lipid profile significantly, number and duration of smoking having correlation with serum lipoprotein levels but type of smoking (cigarette or biddi) doesn't change the outcome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
