The study aimed to evaluate the hepatoprotective potential of aqueous extract of Tamarindus indica fruit against combination of two antitubercular drugs viz. Isoniazid and Rifampicin induced hepatotoxicity in rats. In vitro antioxidant activity of aqueous extract of T. indica by DPPH-HPLC method was found to be 81.48%. Treatment with aqueous extract of T. indica significantly reduced the elevated levels of biochemical markers such as SGOT, SGPT, ALP, bilirubin, TBARS and increased the albumin level as well antioxidant activities of SOD, CAT and GSH in intoxicated rats. The biochemical changes were supported by histological observations. Results of this study clearly demonstrate that aqueous extract of T. indica fruit protects against anti tuberculosis induced oxidative liver damage in rats and thus possess significant hepatoprotective activity. Further, it could be suggested that supplementation with this food extract might prove beneficial in the individuals on anti-TB drugs.

We report herein one-pot synthesis and the antibacterial and antitubercular activities of 2,5-disubstituted-1,3,4-oxadiazole compounds obtained by hybridization of a well-known antitubercular agent isoniazid ( INH) with four broad-spectrum antibiotics belonging to fluoroquinolone ( FQ) class. The work is aimed at designing and developing potential antimicrobial agents having synergistic action due to the coupling of INH and FQ through the biologically active 1,3,4-oxadiazole nucleus. The synthesized compounds are expected to have low toxicity as compared to INH due to the absence of free hydrazide group in the chemical structure of the prepared derivatives. The antibacterial activities of the 1,3,4 oxadiazole derivatives were also tested against several Gram-positive and Gram-negative pathogenic bacterial strains. The antitubercular activity was evaluated against M. tuberculosis H37Rv strain, and the results were compared with that of the positive control INH. The title compounds showed excellent antimicrobial and promising antitubercular activity in comparison to the parent fluoroquinolones and INH, respectively. [ABSTRACT FROM AUTHOR]

Abstract: Spinal tuberculosis constitutes 50% of all musculoskeletal tuberculosis. However, literature regarding congenital spinal tuberculosis is very scanty. Congenital spinal tuberculosis was diagnosed in a two-month-old child on the basis of age at presentation (gibbus since three weeks of age), hepatomegaly, raised ESR, radiological destruction of D10–D11 vertebrae, asymptomatic maternal endometrial tuberculosis and tuberculous histopathology from CT guided biopsy specimen from D10 vertebra. Both child and mother were treated by antitubercular treatment. Child improved symptomatically, gibbus became less prominent and ESR became normal at the end of one year of treatment. Patient had no recurrence during last two years of follow-up. This is the first case of congenital tuberculosis of spine with a documented source of infection from asymptomatic maternal endometrial tuberculosis. CT guided core biopsy from vertebra/aspiration from the paravertebral abscess help in early diagnosis and treatment to reduce neurological morbidity and mortality. Endometrial biopsy help in establishing the diagnosis of congenital tuberculosis and adequate antitubercular treatment in such cases may provide protection to fetus in subsequent pregnancy.
