Forty children treated non operatively for fractures of the femoral shaft were reviewed with regard to differences in limb length after treatment. Follow up duration ranged from two to seven years. The average femoral overgrowth was 0.85cm (range 0 2.5cm) and was influenced by age at the time of fracture. We were not able to find any association between the quantity of overgrowth and race, gender, level or configuration of the fracture.

Objective: To evaluate the hepatoprotective and immunotherapeutic effects of aqueous extract of turmeric rhizome in CCl4 intoxicated Swiss albino mice. Methods: First group of mice (n=5) received CCl4 treatment at a dose of 0.5 mL/kg bw (i.p.) for 7 days. Second group was fed orally the aqueous extract of turmeric at a dose of 50 mg/kg bw for 15 days. The third group was given both the turmeric extract (for 15 days, orally) and CCl4 (for last 7 days, i.p.). The fourth group was kept as a control. To study the liver function, the transaminase enzymes (SGOT and SGPT) and bilirubin level were measured in the serum of respective groups. For assaying the immunotherapeutic action of Curcuma longa (C. longa), non specific host response parameters like morphological alteration, phagocytosis, nitric oxide release, myeloperoxidase release and intracellular killing capacity of peritoneal macrophages were studied from the respective groups. Results: The result of present study suggested that CCl4 administration increased the level of SGOT and SGPT and bilirubin level in serum. However, the aqueous extract of turmeric reduced the level of SGOT, SGPT and bilirubin in CCl4 intoxicated mice. Apart from damaging the liver system, CCl4 also reduced non specific host response parameters like morphological alteration, phagocytosis, nitric oxide release, myeloperoxidase release and intracellular killing capacity of peritoneal macrophages. Administration of aqueous extract of C. longa offered significant protection from these damaging actions of CCl4 on the non specific host response in the peritoneal macrophages of CCl4 intoxicated mice. Conclusions: In conclusion, the present study suggests that C. longa has immunotherapeutic properties along with its ability to ameliorate hepatotoxicity.

Visceral pain is the most common form of pain caused by varied diseases and a major reason for patients to seek medical consultation. It also leads to a significant economic burden due to workdays lost and reduced productivity. Further, long-term use of non-specific medications is also associated with side effects affecting the quality of life. Despite years of extensive research and the availability of several therapeutic options, management of patients with chronic visceral pain is often inadequate, resulting in frustration for both patients and physicians. This is, most likely, because the mechanisms associated with chronic visceral pain are different from those of acute pain. Accumulating evidence from years of research implicates several receptors and ion channels in the induction and maintenance of central and peripheral sensitization during chronic pain states. Understanding the specific role of these receptors will facilitate to capitalize on their unique properties to augment the therapeutic efficacy while at the same time minimizing unwanted side effects. The aim of this review is to provide a concise review of the recent literature that reports on the role of principal ionotropic receptors and metabotropic receptors in the modulation visceral pain. We also include an overview of the possibility of these receptors as potential new targets for the treatment of chronic visceral pain conditions.

The quality of life for women after menopause is one of the key health issues today, and osteoporosis is a silently progressing metabolic bone disease widely prevalent in post-menopausal women in India. Rapid bone loss occurs in post-menopausal women due to hormonal factors that lead to an increased risk of fractures. Thus, the present study was undertaken to observe the serum calcium and alkaline phosphatase (ALP) levels in post-menopausal women as these substances are biochemical markers of bone metabolism. In this small-scale cross-sectional study, 100 samples were taken. Of these, 50 were taken from post-menopausal women (experimental group) and 50 were taken from pre-menopausal women (control group). Serum calcium and serum ALP were measured in the blood samples of both groups. The findings demonstrated that the serum calcium level was significantly lower in the post-menopausal group than in the pre-menopausal group, while the ALP level was slightly higher. Therefore, an increase in bone turnover accelerates bone mass reduction in post-menopausal women, whereas a decrease in bone turnover is associated with the preservation of bone mass.

Epilepsy is one of the most important neurological diseases with prolonged morbidity and disability
leading to profound fi nancial loss. There have not been many studies investigating factors infl uencing
the quality of life in an epilepsy patient in India. This study was conducted among the epilepsy patients
attending a tertiary care hospital in West Bengal, India. Two hundred and four epilepsy patients attending
the Outpatient Clinic of the Department of Neuromedicine, Medical College, Kolkata were interviewed
with the Bengali version of QOLIE 9 (i.e. Quality of life in Epilepsy 9 questionnaire). The mean of
total QOLIE score was 18.02 ± 4.87, the range being 10 to 30. Multiple linear regression analysis
revealed that workdays lost due to epilepsy in last three months, use of two or more antiepileptic
drugs, higher frequency of seizure, and longer time gap between onset of seizure and consultation
with neurologist were signifi cant predictors for poorer quality of life score in the epilepsy patient.

Absorption of dietary fats is generally in the form of emulsions. The present
study assessed the preparation and gastrointestinal absorption efficiency of three emulsions
of mustard oil containing three types of medium chain fatty acids (MCFAs) in a rat model.
Methods: Caprylic acid (C8:0), capric acid (C10:0) and lauric acid (C12:0) were chosen as the
MCFAs. Mustard oil emulsions were formulated using each of the MCFAs and lecithin as
an emulsifier. The characteristics of the formulations including optical microscopy, particle
size, zeta potential analysis and viscosity studies were assessed. Thereafter the intestinal
digestion patterns of the three MCFA rich mustard oil emulsions were compared using a
single pass perfusion test. Results: The particle size of the emulsions varied between 212.70
nm and 312.70 nm. Physical characterisation such as a zeta potential study confirmed that
all emulsions were thermodynamically stable. The absorption study was monitored at
30 min intervals of up to 2 h The absorption of C8:0 emulsion was found to be maximum
(27.78%) followed by C10:0 emulsion (24.81%) and C12:0 emulsion (22.50%). The differences
in absorption efficiency of the emulsions could be attributed to the smaller chain length of
C8:0 which was more rapidly absorbed by the intestine. Conclusion: In vivo gastrointestinal
absorption of MCFA rich mustard oil emulsions was compared; caprylic acid-rich mustard
oil showed the highest absorption rate in comparison to the other two emulsions. Further
in vivo studies are required to establish the mechanism of absorption of structured lipids
containing MCFAs.

A review of serum prostate-specific antigen (PSA) values from January 1994 to May 1997 and their correlation with the histopathology of prostate specimens was carried out in the Department of Pathology, Port Moresby General Hospital. The study has shown that this biochemical investigation has not been properly used for the maximum benefit of the patient population. Remedial measures are suggested to improve the sensitivity and specificity of PSA in a setting with limited resources.

Tissue and organ differentiation is tightly controlled to ensure proper development and function of the growing embryo as well as cells such as lymphocytes that differentiate throughout the adult stage. Therefore it is vital that the genes and the protein they encode that are involved in these processes function accurately. Hence, any mutation or error that occurs along the way can result in extensive damage, which is expressed in various ways in the embryo and can result in immune pathogenesis, including immunodeficiency and autoimmune diseases, when lymphocyte development is altered. A number of studies have been carried out to look at the genes regulating transcription in tissue differentiation, including the transcription factors Pbx1. This gene is of particular interest to us as we have identified that it is associated with systemic lupus erythematosus susceptibility (Cuda et al., in press). This perspective summarizes the known roles of Pbx1 in tissue differentiation as well as our recent findings associating genetic variations in Pbx1 to lupus susceptibility, and we will speculate on how this gene controls the maintenance of immune tolerance in T cells.
