After menopause in women, loss of bone density increases rapidly with estrogen deficiency. Evidence has revealed that this deficiency may be directly correlated with growth hormone (GH) level declining with age. The present study was designed to evaluate the age dependant patterns of GH, insulin-like growth factor-1 (IGF1-1) and insulin-like growth factor binding protein-3 (IGFBP-3) endogenous secretion in postmenopausal women. ⋯ Despite the higher rate of abnormal response to stimulation by clonidine in women aged more than 60 yr, the current study showed no significant correlation between age, and the basal and stimulated GH secretion rate and serum levels of IGF-1 and IGFBP-3 in postmenopausal women.

CYP4F2 and γ-glutamyl carboxylase (GGCX) have small but significant roles in the maintenance dose of coumarinic oral anticoagulants (COAs). CYP4F2 1347 G > A and GGCX 12970 C > G polymorphisms have been used in the pharmacogenetic dosing algorithms of warfarin for Caucasians and Chinese populations. India has a large population with multiple ethnic groups but there are no reports about the frequencies of these polymorphisms in north Indians. In the present study, we aimed to find out the allelic frequencies of CYP4F2 1347 G > A and GGCX 12970 C > G polymorphisms in a north Indian population and relate these to daily maintenance drug dose requirements of COA. ⋯ We report distinct frequencies of CYP4F2 1347 G > A and GGCX 12970 C > G polymorphisms in north Indians but these polymorphisms did not have significant bearing on maintenance dose of acenocoumarol oral anticoagulant in cardiac valve replacement patients.

In recent years, brachytherapy involving permanent radioactive seed implantation has emerged as an effective modality for the management of cancer of prostate. 125 I-Ocu-Prosta seeds were indigenously developed and studies were carried out to assess the safety of the indigenously developed 125 I-Ocu-Prosta seeds for treatment of prostate cancer. ⋯ Our findings have demonstrated that indigenously developed 125 I-Ocu-Prosta seeds may be suitable for application in treatment of prostate cancer.

In current era of limb-salvage therapy, pasteurization of bone sarcomas is receiving growing attention as a potential extracorporeal treatment and cost-effective alternative to allografts and radiation before surgical reimplantation. Detailed in vitro and in vivo pre-clinical study to evaluate efficacy of pasteurization to eradicate malignant cells has not been reported yet. The present study was carried out to assess the efficacy of pasteurization to kill tumour cells both in vitro and in vivo. ⋯ This study has provided a basis to establish pasteurization as being efficacious in ensuring tumour eradication from resected bone tumour specimens. Pasteurized tumour bearing bone can thus safely be used to reconstruct large defects after tumour resection.

a0 ngiotensin II receptor type 1 (AT1) is known to be involved in the pathogenesis of hypertension. t0 his study was undertaken to explore the effect of active immunization against AT1 receptor on blood pressure and small artery remodelling in spontaneously hypertensive rat (SHR). ⋯ Our findings demonstrated that the antibody from SHR immunized with ATR12181 had the effect of reducing blood pressure and target organ protection similar to losartan. Active immunization against AT1 receptor may be a promising strategy in future for the treatment of hypertension.
