  Post mortem examinations of 500 buffaloes were conducted at the slaughter house of Larkana. Out of 500 buffalos 122 (24.4%) were found to be infected with hydatidosis. The organ involvement was as 24.4% in liver, 15.4% in lungs and 13.0% mixed infection (liver and lungs simultaneously). The infection intensity was also recorded as 57.3% livers had slight, 30.3% had moderate and 12.2% had severe infections. In case of lungs 50.6% had slight, 36.3% had moderate and 12.9% had severe infections. The overall investigation showed occurrence of slight infection at the slaughter house of Larkana. The infection occurs through the dogs. Therefore it is suggested that the dogs should not be allowed in the slaughter houses and the cyst infected organs should not be offered to the dogs.

  Oral Contraceptives (OCs) are the most popular type of birth control pills. The study was designed to examine the biochemical changes which occur due to the use of oral contraceptive pills (OCs). The study was based on the questionnaire for having the information of any reproductive history fasting, age, health, nature of menstrual cycle, bleeding, disease etc and blood profiling for biochemical analysis of the women includes High Density Lipoprotein Cholesterol (HDL-C), Low Density Lipoprotein Cholesterol (LDL-C), Total Cholesterol (TC) and Triglycerides (TG). Lipid profiling was carried out by using a commercially available diagnostic test kits. SPSS was used to analyze the data. The results showed statistically significant differences among users of OCs compared to non-users. Total cholesterol (242.92±2.842 mg dL-1), HDL-C (58.65±1.098 mg dL-1), LDL-C (115.84±1.266 mg dL-1) and triglycerides (105.56±2.341 mg dL-1) were significantly higher compared to the Non-users (Total cholesterol 218.49±1.762, HDL-C 48.17±0.543, LDL-C 100.32±0.951 and triglycerides 83.77±2.299 mg dL-1). The result suggests that OCs increase the level of High Density Lipoprotein Cholesterol (HDL-C), Low Density Lipoprotein Cholesterol (LDL-C), Total Cholesterol (TC) and Triglycerides (TG).

Several epidemiological studies conducted on thousands of underground miners suggest that long- term exposure to high radon concentration can increase the risk of lung cancer. Keeping in view the importance of the subject, numerous studies throughout the world have been carried out to measure indoor radon concentration and its resulting doses at occupational and non-occupational sites. The purpose of the current study was to measure indoor radon concentration and its resulting doses received by the students of Azad Kashmir government schools. For this purpose, CR-39 radon detectors were installed in 80 carefully selected schools. The detectors were placed at a height of 3–5 ft. (depending upon average height of students in particular class) from the ground. After exposure of 90 d detectors were etched for 9 h in 6 M NaOH at 70°C and the observed track densities were related to radon concentrations. The measured indoor radon concentration ranged from 22 ± 9 to 228 ± 3 Bq m–3 with a mean value of 78 ± 5 Bq m–3. Based on the measured indoor radon data, the annual effective doses were found to vary from 0.55 ± 0.04 to 0.71 ± 0.03 mSv y–1. The overall mean effective dose for the studied area was found to be 0.63 ± 0.04 mSv y–1. Reported values for radon concentrations and corresponding doses are lower than ICRP recommended limits for workplaces.
