RESUMO

Selective serotonin reuptake inhibitors (SSRI) are the most prescribed antidepressant medications for the treatment of depression and other psychiatric disorders due to their efficacy, tolerability, and safety profile. The dermatological side-effects or cutaneous reactions due to SSRI class of antidepressants is rare. Though there were few case reports of SSRI-induced rash due to fluoxetine, paroxetine, and sertraline, the evidence associated with escitalopram, the highly prescribed antidepressant is comparatively less. The identification and reporting of the drug-related side-effects/adverse drug reactions either serious or non-serious is very important as it will be helpful in understanding, reviewing, and educating the drug-related information before starting medication to the patient.

RESUMO

In the present study fifty genotypes of Brassica juncea were evaluated for heat stress tolerance in terms of biochemical components, in four day old seedlings. Heat shock was given at 45 degrees C for 4.5 hr and thereafter survival percentage, electrolyte leakage and chlorophyll content were estimated. Tolerant genotypes (10) registered survival greater than 65%, moderately tolerant (20) between 35-65% and susceptible (20) less than 35%. Electrolyte leakage was significantly (p < 0.001) higher in susceptible genotypes than in tolerant ones with respect to control seedlings. Chlorophyll content showed no significant variation among the tolerant, moderately tolerant and susceptible genotypes, although it registered a decline in response to heat stress. Lipid peroxidation, assessed by malondialdehyde (MDA) in stressed conditions was 4.66 (MDA g(-1) f. wt. of tissue) in tolerant genotypes, 7.44 (MDA g(-1) f. wt. of tissue) in susceptible genotypes and correlated significantly (r = 0.563) with electrolyte leakage. Increase in POD activity under heat stress was maximum in tolerant class with respect to control. CAT activity showed decrease after heat shock treatment in all the three classes but the decrease was 1.3 fold in tolerant genotypes as compared to 1.6 fold in susceptible genotypes. The non-enzymatic antioxidants glutathione and proline registered a significantly (< 0.01) high value in tolerant genotypes on heat shock treatment in comparison to susceptible genotypes corroborating the role of antioxidants in mitigating the effect of heat stress in Bjuncea. The antioxidants and proline seemed to play role in mitigating the effect of heat stress.

RESUMO

The present study was conducted on lactating Murrah buffalo to assess the effect of crushed flaxseed (a source of omega-3 fatty acids) supplementation (300g/100kg bwt/day for 60 days), over and above the routine feed, on luteolytic signal (PGF2α), luteal function (progesterone) and conception rate. In first experiment, on day 50 post-calving, six non-supplemented buffalo were treated to synchronize time of ovulation using an Ovsynch+Controlled Internal Drug Release (CIDR) protocol followed by intravenous oxytocin treatment (OT; 100IU) on day 15 post-ovulation. Blood samples were collected at 15min interval, 1h before to 4h after OT challenge. Thereafter, the same buffalo were supplemented with flaxseed, treated to synchronize time of ovulation starting on day 35 post-supplementation using the same protocol and subjected to OT treatment and blood sampling on day 15 post-ovulation. The PGF2α response was measured as the venous concentration of 13,14-dihydro-15-keto PGF2α (PGFM). The mean hourly concentration of PGFM subsequent to flaxseed supplemented was less (P<0.05) than in the pre-supplementation period at all the occasions. Flaxseed supplementation did not affect plasma fatty acids and other plasma metabolites except for an increase (P<0.05) in plasma cholesterol and plasma alanine transaminase. In the second experiment, 31 buffalo were randomly assigned to a control (n=16) and flaxseed supplemented (n=15) group. The latter group was supplemented with flaxseed starting from day 15 post-calving. On day 50-post-calving, buffalo of both groups were treated to synchronize time of ovulation among animals as described for the first experiment followed by artificial insemination (AI). Post-AI luteal phase plasma progesterone was greater (P<0.05) in the supplemented group compared to controls. Conception rate on day 63 post-AI was 66.7% in supplemented and 31.2% in controls (P<0.05). The present study indicated the beneficial impact of dietary supplementation of crushed flaxseed on conception rate through attenuation of luteolytic signal and improvement in post-breeding luteal profile.

RESUMO

PURPOSE: The majority of clinical trials have shown that high-grade prostate cancer patients treated with androgen deprivation (AD) plus radiation (RT) have a survival advantage over those treated with RT alone. One possible mechanism for such a favorable interaction is that AD sensitizes cells to radiation. Animal model studies have provided suggestive evidence that AD sensitizes cells to radiation, but this mechanism is difficult to confirm conclusively in vivo. This question was investigated in LNCaP cells grown in vitro. METHODS AND MATERIALS: LNCaP cells were cultured in vitro in Dulbecco's modified Eagle's medium (DMEM)-F12 medium, containing 10% fetal bovine serum (complete medium [CM]). AD was achieved by culture in charcoal-stripped serum (SS)-containing medium. Replacement of androgen was done by adding the synthetic androgen R1881 at 1 x 10(-10) M to SS. Apoptosis was measured with a terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) assay. Clonogenic survival was used to determine overall cell death, and the results were corrected for differences in plating efficiency from the various growth conditions. RESULTS: LNCaP cells were grown in CM, SS, or SS + R1881 medium, and cell counts obtained at 3, 4, and 5 days. Cell number increased exponentially in CM, whereas no increase in cell number was observed in SS medium. Cell counts from growth in SS + R1881 were intermediate between these extremes. Apoptosis was measured to determine if the combination of AD + RT in vitro resulted in supra-additive cell death, as has been previously described in an in vivo model system. The cells were cultured for 3 days before RT and apoptosis quantified 24 h after RT. There was a consistent supra-additive increase in apoptosis in cells exposed to AD + RT (2 or 8 Gy), as compared to either treatment given individually. In contrast, significant radiosensitization by AD was not observed by clonogenic survival even when the conditions of AD were varied. No radiosensitization was observed upon incubation in SS medium for 3, 4, or 5 days before RT, or extending AD after RT for 6 h before plating or 24 h after plating. CONCLUSION: The results show that in LNCaP prostate tumor cells supra-additive apoptosis does not translate into radiosensitization by clonogenic survival. Because clonogenic survival is a measure of overall cell death, either the level of apoptosis is too small a component of overall cell death or the increases in apoptosis occurred in a subpopulation that would have been killed by other mechanisms. Although the findings indicate that AD does not act by sensitizing prostate cancer cells to RT, the additive cell death and growth inhibitory effects of AD + RT are clinically meaningful.
