This study aimed to investigate any inflammatory effect of nicotine on rat embryo by exposing their mothers to different dosages of nicotine during pregnancy. During this experimental study, 32 pregnant healthy Wistar rats were divided into 4 equal groups, including a control and 3 nicotine exposure groups. Injections were performed subcutaneously starting at the first day of pregnancy until parturition. As the dosages of nicotine were increased, the weight gain by pregnant rats and the mean weight of their newborns were significantly reduced. Mean ± SD of hs-CRP was significantly higher among groups exposed to various dosages of nicotine (2, 4, and 6 mg/kg) compared to the control group (P<0.0001) and its increasing rate was also dose dependent. Mean ± SD serum level of IL-6 and TNF-αamong all groups exposed to nicotine, except for 2 mg/kg nicotine injected group, was increased significantly (P<0.0001). Mean ± SD of serum level of TGF-βand nitrite oxide among exposure groups showed significant differences compared to the control group only at the dosage of 6 mg/kg (P<0.0001). The current study showed that exposing pregnant rats to nicotine causes a dose dependent increase in the rate of all the studied inflammatory serum markers among their newborns.

SynopsisIn 17 benzodiazepine (BDZ) dependent in-patients a CT scan was performed before initiation of withdrawal therapy. The evaluation of the ventricular to brain ratio (VBR) by standardized and computerized measurements revealed significantly higher mean VBRs for both high-and low-dose BDZ-dependent patients compared to the mean VBR of an age- and sex-matched control group. In addition, the mean VBR of high-dose BDZ-dependent patients (N = 8) was significantly higher than the mean VBR of low-dose BDZ-dependent patients (N = 9). This difference could not be accounted for by the age of the patients or duration of BDZ-dependency and, therefore, suggests a dose-dependent effect of BDZs on the enlargement of internal CSF-spaces. On the other hand, higher values for the width of external CSF-spaces were found to be related to increasing age of the patients and duration of BDZ-dependency.

The present study was undertaken to establish the diuretic activity of alcoholic and aqueous extract of dried rhizomes of Curcuma amada Roxb in rats. Alcoholic and aqueous extracts of rhizomes were administered to experimental male Wistar rats orally at doses of 250 and 500 mg/kg and compared with furosemide (10 mg/kg) as the reference standard. The parameters measured for diuretic activity were total urine volume, urine electrolyte concentration such as sodium, potassium and chloride have been evaluated. The rats treated with alcoholic and aqueous extract of Curcuma amada in a dose of 250 and 500 mg/kg showed higher urine output when compared to the respective control. Both alcoholic and aqueous extracts have showed a significant dose-dependent increase in the excretion of electrolytes when compared to the control group. The result indicates that alcoholic and aqueous extract is an effective natriuretic and kaliuretic diuretic, which supports the traditional claim about the Curcuma amada Roxb being used as diuretics.

The objective of the present study was to evaluate bone and cardiac abnormalities and symptoms and signs of thyroid hormone excess in women with subclinical hyperthyroidism (SCH) aged < 65 years. Forty-eight women with SCH were evaluated. The control group consisted of 48 euthyroid volunteers. The mean symptom rating scale score was significantly higher in patients. Cardiac involvement, both morphological and affecting systolic and diastolic functions, was also observed in patients. Women with SCH showed a significant increase in serum markers of bone formation and resorption. In addition, bone mineral density (BMD) was lower in the femoral neck but not in the lumbar spine in patients before menopause, whereas a lower BMD was observed at both sites in postmenopausal patients. SCH is not completely asymptomatic in women aged < 65 years, and is associated with heart abnormalities and with increased bone turnover and reduced BMD even before menopause.

PURPOSE: Determine the effects of the MSG (monosodium glutamate) in the offspring of pregnant rats through the comparison of the weight, NAL (nasal-anal length) and IL (Index of Lee) at birth and with 21 days of life. METHODS: Pregnant Wistar rats and their offspring were divided into 3 groups: GC, G10 and G20. Each of the groups received 0%, 10% and 20% of MSG, respectively from coupling until the end of the weaning period. RESULTS: Neither weight nor NAL were different among the groups at birth. The group G20 at birth had an IL lower than the group GC (p<0,05) and with 21 days of life presented weight and NAL lower than the groups G10 and this lower than the GC (p<0,01). Otherwise the G20 at 21 days of life had the IL similar to the other two groups. The weight profit percentage from birth to the 21st day of life was lower in the G20 regarding the other two groups (p<0,01). The G20 had a NAL increase percentage from birth to the 21st day of life lower than the G10 and this lower than the GC (p<0,01). CONCLUSIONS: MSG presented a dose-dependent relation in the variables weight and NAL. It caused a decrease in the growth pattern as well as in the weight gain pattern until the 21st day of life. The IL of the group 20% had an increased in relation to the control group after 3 weeks of follow up.

<p>In addition to known risk factors, the role of different micronutrients such as selenium in diabetes incidence has been proposed. Some previous studies have shown an association of selenium deficiency and type 2 diabetes mellitus, while other studies have not confirmed such a relationship. The aim of this study was to evaluate serum level of selenium in patients with Type 2 diabetes compared with the control group. This cross-sectional study was carried out on patients with type 2 diabetes in Zahedan, southeastern Iran. One hundred newly diagnosed type 2 diabetic patients were evaluated for serum selenium level. One hundred subjects from the general population who had normal fasting blood sugar levels were selected as the control group. The control group subjects were matched in pairs with each of patients on the basis of sex, age (± one year), and body mass index (±1). Serum level of selenium was determined by spectrometry method. Results were compared using t-test. The mean serum level of selenium in patients was 94.47±18.07 µg/L whereas in control group was 142.79±23.67 µg/L. The mean serum level of selenium was significantly different between the two groups (P&lt;0.001). Serum levels of selenium in diabetic patients with significant difference statistically were lower than the control group. In order to evaluate serum level of selenium in patients with diabetes, studies with larger sample size are required. Likewise, prospective studies along with selenium supplementation and investigating its effect on incidence of diabetes are accordingly needed.</p>

Background: Inflammation is linked to the aetiopathogenesis of Metabolic syndrome (MetS). Objective: To assess the ability of high sensitivity C-Reactive Protein (hs-CRP), Tumour Necrosis Factor-alpha (TNFα) and Interleukin-6 (IL-6) to predict MetS. Methods: A case-control study involving 123 subjects with MetS (cases) and age-matched 123 subjects. without MetS (controls) was conducted. The levels of TNFα, IL-6, and hs-CRP between independent groups were compared. The Receiver Operative Characteristic Curve was used to assess the ability of inflammatory markers to discriminately identify MetS. Results: The mean age of the case and control groups was 49.9±0.9 years and 48.1±1.1 years (p = 0.274) respectively. The median levels of TNFα, IL-6 and hS-CRP were significantly higher among the cases than the control group in both genders (p <0.001). There was a significant increase in the serum values of the markers with increasing components of MetS (p <0.001). The Area Under the Curve of TNFα, IL-6 and hs-CRP was > 0.9 in both males and females. Conclusion: TNFα, IL-6, and hs-CRP identified MetS. There is a need for further studies to determine the inflammatory marker most predictive of MetS.

This study was designed to assess tumour necrosis factor-alpha and creatinine levels in Echis ocellatus bite victims. A total of 50 subjects were recruited. Out of this number, 40 were victims of E. ocellatus bite and the remaining 10 were non-victims of snake bite who served as the control group. Blood samples were collected from the victims within 24 hours of the snake bite and EchiTAb-G antivenom administered within the same period. Another batch of blood sample was collected 48 hours post-administration of the anti-venom. Tumour necrosis factor-alpha (TNF-alpha) levels were estimated by the Enzyme Linked Immunosorbent Assay technique while creatinine levels were determined using kinetic-spectrophotometric procedure. The mean serum levels of tumour necrosis factor-alpha and creatinine were significantly increased in E. ocellatus bite victims compared with the control group (P<0.05). Furthermore, the mean serum level of TNFalpha was significantly lower in E. ocellatus bite victims, post-administration of anti-venom, compared with the pre-administration of anti-venom (P<0.05). In contrast, no significant difference was observed in the mean serum level of creatinine in E. ocellatus bite victims, post-administration of anti-venom, compared with the pre-administration of anti-venom (P>0.05). Moreover, the mean serum level of creatinine was found to be significantly increased in E. ocellatus bite victims, post-administration of anti-venom, compared with the control group (P<0.05), while no significant difference was observed in the mean serum level of tumour necrosis factor-alpha in E. ocellatus bite victims, post-administration of anti-venom, compared with the control group(P>0.05). A positive correlation existed between tumour necrosis factor-alpha and creatinine levels in E. ocellatus bite subjects (r= 0.782). Echis ocellatus bite is a risk factor for renal damage indicated by an elevated serum creatinine, thus health authorities should make EchiTAb-G anti-venom freely available in health facilities and administered as quickly as possible to reduce the risk of renal damage in Echis ocellatus bite-prone areas.

This study was conducted to investigate the effect of intracerebroventricular administration of endothelin (EDT), a novel potent vasoconstricting peptide, on blood pressure in conscious rats. The lateral cerebral ventricle of male Wistar rats was cannulated, and the femoral artery was also cannulated to measure the mean arterial blood pressure (MABP) and heart rate (HR). EDT dissolved in 10 microliters of artificial cerebrospinal fluid (ACSF) (8.25-66 pmol icv) provoked a dose-dependent increase in MABP. EDT also increased HR, although the effect of 66 pmol was variable. Intracerebroventricular ACSF did not provoke any effects on MABP and HR. Intracerebroventricular EDT also provoked contralateral rotational behavior. Pretreatment with 2 mg/kg iv phenoxybenzamine significantly suppressed the 16.5 pmol icv EDT-induced increase in MABP. Moreover, 16.5 pmol icv EDT markedly increased plasma epinephrine and norepinephrine concentration. These results indicate that EDT has a central pressor action, and the action might be mediated, at least in part, by catecholamine release to the periphery. EDT might play a role in the central control of blood pressure, although the physiological implications have not yet been determined.

This work assess serum levels of soluble Fas form (sFas) in patients with different stages of laryngeal squamous cell carcinoma(LSCC) to investigate its prognostic significance. We correlate its levels with the morphological changes of peripheral blood cells via buffy coat examinatin. The study population included 70 patients clinically diagnosed and pathohistologically confirmed LSCC in addition to 20 healthy controls. According to TNM classification 33(47.1%) patients were in stage I (group I) and 24(34.3%) in stage II (group II), 13(18.5%) in stage III (group III). The results revealed that the mean serum level of sFas (pg/ml) in the control group was 51.2, in group I was 66.33, in group II was 81.33 and in group III was 112.45. Statistical analysis of the mean of sFas by ELISA test in the patients' groups in comparison to the control revealed a significant increase of both group II and III in comparison to the control group (P < 0.01) but there was no significant difference (P > 0.05) between group I in comparison to either the control or group II. There was a significant difference (P < 0.05) between group I in comparison to group III. LM examination revealed massive extent of the apoptotic cells in group III when compared to both group I and group II. EM examination of the buffy coat revealed apoptotic changes, mainly in the peripheral blood mononuclear cells (PBMNCs), represented by surface membrane ruffles and blebs with clumped nuclear chromatin and vacuolated cytoplasm. In conclusion, this study may help us to better understand one of the escape mechanisms in cancer larynx. This mechanism is represented by the significant increase in both the serum level of sFas and the morphological apoptotic changes that detected in PBMNCs. Soluble Fas may contribute to the progression of laryngeal cancer. It can be used as an attractive target for anticancer therapy and may be considered as a marker of disease progression and poor prognosis in laryngeal cancer.

Objectives: Drugs can cause undesired effects on the fetus during pregnancy, especially embryonic/organogenesis which could lead to defects in the fetus because some types of drugs can penetrate the placenta and will undergo biotransformation into a highly reactive compound that has the potential to become a teratogenic compound. The aim of this research was to examine the teratogenic effect of bintangur leaves (Calophyllum soulattri Burm. F) ethanol extract to Sprague Dawley strain white rats. Methods: The white rats are divided into four treatment groups: Control group was given carboxymethyl cellulose Na 1%, comparison group was given trimethoprim 360 mg/kg BW, C. soulattri leaves ethanol extract (CLE) 100 mg/kg BW, and CLE 500 mg/kg BW. The treatment was administrated since organogenesis period. Cesarian section was performed to pregnant rat at the 20th day to separate the fetuses. Observation covered body weight of pregnant rats, fetal biometric, morphological malformation, and skeletal formation. Results: CLE 100 mg/kg BW and 500 mg/kg BW did not cause any change in the number of a living fetus, body weight, and length of fetuses like the comparison group. Both doses of CLE shown have a normal skeletal formation. Resorption was found in the comparison group and CLE 100 mg/kg BW with the percentage was 65.21% and 6.67%. It was found that there is no significant difference (p<0.05) between both doses of CLE compared to control group. Conclusion: From the results, it is concluded that CLE did not have the teratogenic effect.
