Role of fine‐needle aspiration cytology in tuberculosis of bone

This study was designed to evaluate the role of fine‐needle aspiration cytology (FNAC) in diagnosis of skeletal tuberculosis (TB). In this retrospective study, 20 cases were retrieved over a 10‐year period in which a cytologic diagnosis of osseous TB was rendered. The aspirations were performed with a 22‐gauge needle attached on a 20‐ml syringe after taking into consideration the radiological findings. The cytologic findings were subdivided into the following categories—epithelioid cell granulomas with necrosis, epithelioid cell granulomas without necrosis, and necrosis only. These cases were either with or without AFB positivity. The smears showed epithelioid cell granulomas in 23 cases (85.2%), multinucleate and Langhans' giant cells in 15 cases (55.6%), and inflammatory cells were noted in the background in 15 cases (55.6%). AFB was positive in six cases (22.7%). FNA provides a simple and safe outpatient procedure for the diagnosis of osseous TB and obviates the need of an open biopsy. Diagn.

Development of in vitro screening system for assessment of antifilarial activity of compounds

Evaluation of antifilarial activity of new potential agents in vivo is extremely time consuming and uneconomic. In the present study effort has been made to develop an in vitro screening method using Acanthocheilonema viteae, a subcutaneously dwelling rodent filariid with anaerobic metabolic characteristics like human filariids, W. Bancrofti/Brugia malayi as test parasite. Motility test and tetrazolium (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide, MTT) based colorimetric assay were used as parameters in in vitro assay. Results showed that 92.3% of compounds (in vivo active) could be picked up in the in vitro assay when both adults and microfilarae (mf) were used simultaneously. Mf and adult stages separately detected, respectively, 84.6 and 69.2% of in vivo active compounds. The adults and mf separately and both the life stages together exhibited, respectively, 80.0, 50.0 and 80.0% false positive results in the in vitro test with in vivo inactive compounds. It is felt that mf stage when used in in vitro test using motility and MTT assays as parameters would be useful in primary screening of new potential filaricides.

Anomalous Lateral Rectus Muscle Band in a Case of Duane Retraction Syndrome

Anomalous orbital structures are suspected in restrictive strabismus with features of severe globe retractions, overshoots, or synergistic movements. We report a case of suspected Duane syndrome that was found to have an anomalous band beneath the lateral rectus muscle. Such abnormal structures are rare, but it is important to identify and manage them to optimize outcomes.     

Radioprotective Efficacy of Aloe vera Leaf Extract

Radiomodifying effects of the leaf extract of Aloe vera were observed on the testes of Swiss albino mice at 50 and 100 mg/kg dose levels. This extract was non-toxic when injected up to 800 mg/kg, and significant enhancement in survival time of the irradiated group was observed. In addition, treatment reduced radiation-induced damage to germ cells and loss in body weight.
