Protective role of diet supplements Spirulina and Tamarind fruit pulp on kidney in sodium fluoride exposed Swiss albino mice: Histological and biochemical indices.

Fluoride toxicity through potable water, particularly ground water, is not uncommon in countries such as India, China, Iran, Iraq, Turkey, parts of Africa and Afghanistan. Kidney being the main organ involved in fluoride removal, it accumulates considerable amount of fluoride. Here, we report toxic effects of oral exposure of Swiss albino mice to fluoride (sub-acute: 190 mg/kg body wt. for 7days; and sub-chronic: 94 mg/kg body wt. for 90 days) and recovery of sub-chronic fluoride exposed mice after 90 days of sodium fluoride (NaF) withdrawal. The role of diet supplements (Spirulina and tamarind fruit pulp @ 230 mg/kg body wt. independently as well as in combination) in amelioration of fluoride toxicity has also been screened. Compared with controls, feed intake decreased from 3-43%, body wt. 4-18%, and kidney wt. 5-12% in treated mice (except diet supplement groups of sub-chronic exposure) while their water intake increased from 4-43%. Histopathological changes in the cortical region of kidney in fluoride treated mice were as follows: dilation of bowman’s capsule and thickening of its parietal and visceral layer; alterations in glomeruli size and their sclerotization; increase in bowman’s space; proliferation of mesangial cells; reduction in podocyte counts; and dilation of proximal and distal tubules. Fluoride exposure altered tissue biochemistry (protein, acid phosphatase and alkaline phosphatase content) and increased urea (23-58%) and creatinine content (14-127%) in the serum. Sub-acute exposure was found more toxic. The diet modulation not only reduced fluoride toxicity but also led to better recovery of treated mice after withdrawal, especially in combination.

Perception of quality in a Radiation Oncology Department: Is it different for patients and health care providers.

AIM: Patient satisfaction is increasingly being identified as an important benchmark in health care industry. Studies addressing patients’ perceptions of quality are available but there is paucity of data regarding the perception of health care providers towards their own services. This study was undertaken to compare the satisfaction level between the patients and the staff from a Radiation Oncology Department. MATERIALS AND METHODS: A common 16‑item questionnaire addressing various aspects of patient care was served to 40 patients and 40 staff members. The responses were statistically evaluated to assess the satisfaction level among the two groups and the scores were compared to assess the agreement between two groups. RESULTS: Overall, satisfaction level of both groups regarding quality of services ranged from “good” to “excellent”. A high level of agreement was observed between the two groups. The physician’s ability to give an explanation to patients, helping attitude of the staff and the staff’s concern for patient safety were the most satisfying features of the department while inconvenience during scheduling of appointments, billing and registration process, status of the changing rooms and inter‑department coordination were the least satisfying features. CONCLUSION: A high level of satisfaction may be achieved from the consumers if service providers are trained to assess the needs and expectations of consumers and to critically evaluate themselves. The service provider’s perception regarding their own services may serve as a preliminary indicator of overall quality. Future studies with more participants in different setting may further explore this hypothesis.

Superovulation and embryo recovery in rabbits (Oryctolagus cuniculus) using different doses of pregnant mare serum gonadotrophin (PMSG).

Present investigation was conducted to study the ovarian response and embryo recovery using different PMSG dose levels. Six rabbits each were assigned randomly to treatment 1 (PMSG 50 IU + hCG 100 IU), treatment 2 (PMSG 75 IU + hCG 100 IU) and the control group (no hormone administered). PMSG injection (im) was followed 68 hr later by natural mating to a fertile rabbit buck and human chorionic gonadotrophin (hCG) injection iv post coitum. Embryos were recovered 96 hr post coitum by a modified surgical method. Mean number of ovulations in the control group differed significantly from treatment 1 and 2, but no significant difference was observed between treatments 1 and 2. Mean embryo recovery percentage was lowest in treatment 2 and highest in the control group. The higher dose PMSG (treatment 2) was observed to be more disturbing in terms of recovery of embryos as well as their morphology.
