Background: The menace of substance abuse is not only a socially unacceptable reality, but in its entirety is a disease and emerging as a major public health challenge. Objective: To study the socio-demographic and clinical profile of patients attending the drug de-addiction centre. Methods: A descriptive study was undertaken in a drug de-addiction centre at the Police Hospital in Srinagar, and all patients (198) who were admitted during this period were interviewed. Results: The mean (SD) age of patients was 26.8 years (SD 7.37), and over half (56%) belonged to the lower-middle social class. Poly-substance abuse was seen in 91.9%; medicinal opioids and cannabis were the most common substances abused. Most common age of initiation was 11–20 years (76.8%), with peer pressure and relief from a negative mood state being the most common reasons given for starting the drug(s). Prevalence of a co-morbid psychiatric disorder was high, on the order of 49.5%. A high rate of volatile substance use was observed among adolescents (54.5%). Conclusion: A pattern of poly-substance abuse was found to be quite common in patients, and use of volatile substances at a very young age emerged as a new trend. The dreadful repercussions of substance abuse justify the urgency to evolve a comprehensive strategy.

Objective: To elucidate the pattern of inheritance and determine the relative magnitude of various genetic effects for maturity and flowering attributes in subtropical maize. Methods:Four white grain maize inbred lines from flint group of corn, two with late maturity and two with early maturity, were used. These contrasting inbred lines were crossed to form four crosses. Six generations (P1, P2, F1, F2, BC1, and BC2) were developed for each individual cross. These were evaluated in triplicate trial for two consecutive years. Results: Both dominance gene action and epistatic interaction played major role in governing inheritance of days to pollen shedding, 50% silking, anthesis silking interval and maturity. Conclusions: Preponderance of dominance gene action for these traits indicated their usefulness in hybrid programs of subtropical maize.

Bilharziasis is a tropical parasitic disease caused by different species of the genus Schistosoma. One species, S. haematobium, is widely spread in Sudan. There is a scarcity of information about S. haematobium infection among the fishermen in the country. Therefore, this study was designed to determine the prevalence of S. haematobium infection among fishermen, and the immune status among non-infected fishermen in two villages, El Hadib and Hawer-Ajowel at the White Nile state in Sudan. A cross-sectional survey was conducted among 119 fishermen in addition to 20 samples from non-endemic area which were included as a control group. Urine samples were examined by sedimentation method and faecal samples were examined by the Kato Katz method and formalin-ether concentration technique. Blood samples were examined for enumeration of IgE antibody and cytokines, interferon Gamma (IFN-γ), Tumor Necrosis Factor (TNF) and Interleukin10 (IL–10) levels using ELISA. The result of the study indicated that the overall prevalence of S. haematobium among the fishermen was 35 (29.41 %). Of the 35 positive participants, 23 (65.71 %) were infected for the first time, and 12 (34.29 %) for the second time (re-infection). Twenty-four candidates of the non-infected fishermen were included in the immunological study. The total IgE mean titer was 282.90 ±70.93 iu/ml, IFN-γ mean level was 9.62±4.60 pg/ml. TNF, 114.64±46.63 pg/ml and the IL–10 was 1.51±0.58 pg/ml. High prevalence of S. haematobium exists among fishermen and the non-infected fishermen from the endemic area showed high immune response similar to those exposed to the infection.
