Item Human toxocariasis and ascariasis: concomitant parasitism in Srinagar, Kashmir, India.(2002-07-06) Ahmad, Bashir; Bhatti, Gurjeet; Thokar, M A; Malla, NancyHuman toxocariasis caused by Toxocara canis is common in both developing and developed countries and leads to visceral larva migrans with high morbidity and mortality. Ascariasis caused by Ascaris lumbricoides, too has global distribution and in India, high prevalence rate has been reported in Kashmir (J & K State). Both nematode parasites, Toxocara canis and A. lumbricoides require similar biological and environmental conditions for the development of eggs in soil. Therefore, the present study was attempted to detect the antibody response to T. Canis excretory-secretory (ES) antigen by enzyme linked immunosorbent assay in patients attending Sher-I-Kashmir Institute of Medical Sciences, Soura, Srinagar, Kashmir to assess the magnitude of human toxocariasis in Kashmir, the highly endemic area of ascariasis. Interestingly, it was observed that 38 (82.60%) out of 46 patients harbouring Ascaris Iumbricoides had positive antibody response to T. Canis ES antigen while none of the 15 normal healthy subjects from the same endemic zone, 25 from low endemic zone Chandigarh and 15 from other parasitic infections (hookworm, hydatidosis, cysticercosis) indicated detectable positive response. Majority of the ascariasis positive patients studied were in the age group of 21-40 years. However, one ascariasis patient studied in the age group of 1-10 years (4 years old) had also positive antibody response to T. Canis antigen. This study is the first report of human toxocariasis in Kashmir, India, an endemic zone for ascariasis and emphasizes the need for detailed epidemiological study for the ultimate prevention and control of this diseaseItem Influence of Ozagrel Sodium along Atypical Anti-psychotic Drug on Red Blood Cell Distribution Width in Rats with Minimum and Maximum Dose Comparison(Sumathi Publications, 2019-06) Bashir, Muhammad Irfan; Saleem, Uzma; Anwer, Fareeha; Ahmad, BashirObjective: To study the activity of ozagrel sodium alone and in combination with the atypical antipsychotic drug on Red blood cell distribution width (RDW-CV) along with different doses and their comparison in rats. Method: This experimental study consisted of 120 albino rats of both gender, they were of 310-350 g, there were 10 groups which consists of each of 12 rats (n=12). Rats were treated with an accurate dose of ozagrel and atypical antipsychotic (Zuclopenthixol cis isomer of clopenthixol) alone and in combination for 3-weeks (21 days). We obtained blood sample at 0, 7th, 14th and last day of the study. Red blood distribution widths were measured from blood tests by utilizing standard medical laboratory technique. Red blood cell distribution width (RDW-CV) was measured by using the coefficient of variation indicator. Results were gathered and summarized by applying statistics. The comparison was formed between all days value to zero-day. Results: Minimum dose treated groups by both medications showed an increase and RDW-CV, but maximum dose showed p<0.001 decreases in RDW-CV in individual groups of drugs treatment and in case of RDW-CV maximum dose showed an increasing trend with p<0.001 in the combination groups. Conclusion: Maximum dose of ozagrel may cause a decrease in RDW-CV alone and it may cause an increase in (RDW-CV) with a combination of atypical antipsychotic drug.Item Rationalization of Traditional Uses of Berberis lycium in Gastrointestinal Disorders.(2013-10) Rahaman, Muhammad Shafeeq ur; Chaudhary, Mueen Ahmad; Ahmad, Bashir; Alamgeer, AlamgeerAims: Berberis lycium (Sumbal) is abundantly available in the northern areas of Pakistan and extensively used in local practice for the treatment of several human diseases. The objective of this study was to explore pharmacological basis for its use in gastrointestinal disorders. Materials and Methods: Crude aqueous (Bl.Aq) and methanolic (Bl.Meth) extracts of B. lycium were studied on isolated gut preparations of rabbit (jejunum) and guinea pig (ileum) by using in-vitro techniques. Tissues were mounted in tissue organ baths assembly containing physiological salt (Tyrode's) solution, maintained at 37ºC and aerated with carbogen, to assess the spasmogenic and spasmolytic effect and to find out the possible underlying mechanisms. Responses were measured on BioScience Powerlab data acquisition system by using isotonic transducers. Results: Phytochemical analysis indicates the presence of alkaloids, tannins and saponins in Bl.Aq and Bl.Meth. when tested on spontaneously contracting isolated rabbit jejunum, showed a dose-dependent spasmogenic effect at lower concentration (0.01-0.1 mg/mL) and (0.01-0.03 mg/mL), which was followed by spasmolytic effect at higher concentration (0.3-1.0 mg/mL) and (0.1-0.3 mg/mL) respectively. Pretreatment of the tissue with atropine (0.1 μM) partially suppressed the contractile effect. Bl.Aq and Bl.Meth caused complete inhibition of high K+ (80 mM)–induced contraction at 0.3 mg/mL and 0.1 mg/mL respectively and also produced a dose-dependent (0.01-0.03 mg/mL) rightward shift in the Ca++ concentration-response curve, similar to verapamil. When tested in bolus protocol on isolated guinea pig ileum, Bl.Aq and Bl.Meth caused a dosedependent spasmogenic effect at 0.01-0.1 mg/mL. Pretreatment of tissue with atropine (0.1 μM) partially suppress the contractile effect. Conclusions: Results indicate that spasmogenic effect was partially mediated through cholinergic activity and spasmolytic effect was mediated through calcium channel blocking activity (CCB), explain its traditional uses in diarrhea, intestinal cramps and other gastrointestinal intestinal disorders.
