Background and Aims: Postprandial increase of 3-hydroxytryptamine (5-HT) has been implicated in irritable bowel syndrome (IBS). There is evidence that nitric oxide (NO) may act as a mediator of 5-HT-evoked secretions in the colon. Our aim is to investigate the role of urinary 5-hydroxyindole acetic acid (5-HIAA) and plasma NO levels (with diarrhoea) in IBS patients. Methods: Nineteen (with constipation) IBS patients (group 1), 22 IBS patients (group 2) and 18 healthy controls (group 3) were included in the study. The diagnosis of IBS was made according to the Rome I Criteria. The urine was collected for determination of 5-HIAA and venous blood was collected from each subject for the measurement of plasma NO levels. Results: The levels of urinary 5-HIAA mmol/day and plasma NO mmol/l of group 1 (22,4±2,2 and 29,4±2 respectively) were significantly higher than group 3(14,2 ± 2,3 and 21,3 ± 2,1 respectively) (p =0,036 and p =0,019 respectively). The NO level of group 1 was also significantly higher than group 2(21,8 ± 1,9) (p = 0,021). The 5-HIAA level of group 1 was higher than group 2 (15,2, ± 2,1) and the difference was marginally significant (p = 0,055). There was no difference between group 2 and group 3 with respect to 5-HIAA and NO levels. Conclusions: The results of this preliminary study lend support to the involvement of 5-HT in some symptomatology of diarrhoea predominant IBS. Furthermore, NO may be one of the effector mediators of the 5-HT-induced symptoms in these patients.

Background: Adverse effects of available medications for osteoarthritis (OA) and rheumatoid arthritis (RA) necessitate development of safer and effective alternative medicinal substitutes. The present study was conducted to evaluate analgesic activity of Ariflex liniment (conceptualized and developed by Ari Healthcare Pvt. Ltd.) in comparison with diclofenac gel by using acetic acid induced writhing model.Methods: Albino mice of either sex weighing 20-25 g were taken and divided into 3 groups with 5 animals in each group, i.e., group 1 (control group), group 2 (diclofenac gel) and group 3 (Ariflex liniment). After 1 hour of topical application of study drugs writhing was induced in mice using intra-peritonial injection of 1% acetic acid in volume of 0.1 ml/10 g body weight. Then the writhing episodes were recorded for 30 minutes and results were noted.Results: In the control group, the total number of  writhes were 260±29.73 (mean±S. E. M.). The total number of writhes was 12.17±11.81 (mean ± S. E. M.) in diclofenac group. In Ariflex liniment group, not a single animal felt pain, hence there were no writhes recorded. When compared to control group, the difference in number of writhes was statistically significant. The analgesic activity of Ariflex liniment was found to be superior to that of diclofenac gel used as standard drug.Conclusions: It can be concluded that Ariflex liniment possesses analgesic activity.

AIM: The current study aimed to provide a method for juvenile nasopharyngeal angiofibroma embolization using Glubran glue in patients with low stage tumor. This method not only has less blood loss and good visualization but also impose a low cost, where no pre-operative embolization complications were found for this procedure. METHODS: Between 2012 and 2014, 30 patients with angiofibroma undergoing endoscopic surgery. Age, sex, tumor stage, average blood loss, complications, length of hospitalization, and recurrence rate of the tumor were the main measured outcomes. Furthermore, 30 patients were divided into three groups with matched age, sex, and tumor staging. Group 1 received glue (Glubran), while Group 2 selected for study without glue and embolization and pre-operative embolization was considered for Group 3. RESULTS: Based on the amount bleeding, the mean blood hemorrhage in Groups 1, 2, and 3 was 510, 1655, and 800 ml, respectively, the difference of hemorrhage between Groups 1 and 2 was found to be statistically significant (p = 0.007). Blood loss in Group 1 was found to be less than Group 3, but the difference of hemorrhage between Group 1 and 3 was not statistically significant (p = 0.678). No blood transfusion and complication were recorded for individuals in Group 1. The recurrence was found in 1 patient (10%) in both groups of 2 and 3, and no patient (0%) in Group 1. CONCLUSIONS: The direct intraoperative embolization technique with glue was capable of providing a more complete and targeted embolization of the tumor. Some advantages can be mentioned for this technique, including decreased blood loss, less radiation exposure, lower rates of complications, and recurrence, as well as shorter hospitalization time, the ease of procedure with a spinal needle and low cost.

OBJECTIVE: This study evaluated the use of plasma, bone surface (periosteal) and whole bone as biomarkers of chronic fluoride (F) exposure. METHODS: Forty male Wistar rats were assigned to 4 groups (n=10/gr) that differed according to the F concentration they received in the drinking water. Groups 1, 2, 3 and 4 received water containing 0 (control), 5, 15, and 50 mg F/L, respectively. The rats were killed at 120 days of age. Plasma and femur were collected and analyzed for fluoride with the ion specific electrode by the direct method or after hexamethyldisiloxane-facilitated diffusion. Data were tested for statistically significant differences by ANOVA and linear regression (p<0.05). RESULTS: Mean (± SE) plasma F concentrations ranged from 0.030 ± 0.002 to 0.187 ± 0.013 (mg/mL). The concentrations in surface and whole bone ranged from 610 ± 32 to 4,693 222; and 647 ± 22 to 3,439 ± 134 µg/g, respectively. The surface/whole F concentration ratios were 0.941, 1.414, 1.173 and 1.377, for groups 1, 2, 3 and 4 respectively. For plasma and whole bone, the difference among all groups was statistically significant, except for group 2 compared to group 1. For bone surface, all groups differed from each other except for group 2 compared to group 3. A significant positive correlation was found between bone surface and whole bone F (r²=0.94), as well as between plasma and bone surface (r²=0.71) and plasma and whole bone (r²=0.74). CONCLUSIONS: Data suggest that both bone surface and whole bone are suitable biomarkers of chronic F exposure in rats and plasma may be used as indicator of bone fluoride levels.

Background and objectives: Cryotherapy is a method of treatment using cold application. This study aimed to evaluate postoperative clinical and hematological parameters and pain associated with total knee arthroplasty in patients and compared cryotherapy to the conventional method of cold ice pack compressions. Materials and Methods: Between January 2015 and January 2016, 90 patients who underwent total knee arthroplasty for grade 4 gonarthrosis were prospectively evaluated. The patients were divided into three groups (n = 30, each): Group 1, cryotherapy was applied in the pre- and postoperative periods; Group 2, cryotherapy was applied only in the postoperative period; and Group 3 (control group), only a cold pack (gel ice) was applied postoperatively. In all groups, pre- and postoperative evaluations at 6, 24, and 48 h, hemorrhage follow-up, knee circumference measurement, visual analog scale pain score, knee circumference, and temperature measured by thermal camera were recorded. Results: Of the 90 patients, 10% were men and 90% were women. The mean age was 64.3 ± 8.1 (range: 46–83) years. The patella upper end diameter values were significantly lower in the postoperative period in Groups 1 and 2 than in Group 3 (p = 0.003). Hemoglobin levels at 24 and 48 h postoperatively were significantly lower in Group 3 than in Group 1 (p < 0.001, each) and Group 2 (p = 0.038, p < 0.001). At 6, 24, and 48 h follow-ups, pain values were significantly lower in Group 2 than in Group 3 (p < 0.001). Preoperative 6, 24, and 48 h temperature values were significantly lower in Group 1 than in Group 3 (p < 0.001 for each). It was found that the difference between preoperative and postoperative knee flexion measurements was significantly different in both groups or the difference between the groups was changed in each period (p < 0.001). Conclusions: Postoperative cryotherapy is a potentially simple, noninvasive option and beneficial for the reduction of reducing pain, bleeding, length of stay, analgesic requirement and swelling after total knee arthroplasty. Moreover, there was no early or late prosthesis infection in cryotherapy groups, which may be considered as an additional measure to prevent prosthesis infection.

SUMMARYThis study reports an outbreak of oriental theileriosis in dairy cattle imported to Vietnam from Australia. Following clinical and pathological diagnoses, a total of 112 cattle blood samples were divided into three groups and tested using multiplexed tandem PCR. Group 1 were from aborted heifers in Vietnam; group 2 were from cattle before shipment from group 1 cattle and group 3 were from the same batch of cattle but transported to Taiwan. Theileria orientalis DNA was detected in 72·3% cattle. The prevalences of T. orientalis in groups 1, 2 and 3 were 77·6, 86·9 and 57·5%, respectively, and the difference in prevalence was significant between groups 1 and 3 (P < 0·0001). The infection intensities of genotypes chitose and ikeda of T. orientalis were higher in groups 1 (57 721 and 33 709, respectively) and 3 (5897 and 61 766, respectively) than those in group 2 (2071 and 6331, respectively). Phylogenetic analyses of the major piroplasm surface protein sequences revealed that genotypes chitose and ikeda determined herein were closely related to those previously reported from Australia. This first report of an outbreak of oriental theileriosis in imported cattle emphasizes improved measures for the export and import of cattle infected with T. orientalis.

ABSTRACTRecalcitrant dermatophytoses are on the rise and recent publications have documented high minimum inhibitory concentrations (MICs) to TRB and squalene epoxidase (SQLE) mutations. However, literature correlating the laboratory the data with clinical response is lacking.This study was conducted to study the clinico-mycological profile of tinea corporis and cruris, including antifungal susceptibility testing (AFST) and SQLE mutation analysis and correlate these with clinical response to TRB. Skin scrapings of patients with tinea corporis with/without tinea cruris were subjected to species identification, AFST and SQLE gene analysis (on 15 isolates). KOH confirmed cases were started on TRB 250mg once a day (OD). If >50% clinical clearance was achieved by 3 weeks; the same dose was continued.(Group 1). If clinical clearance at 3 weeks was <50%, the dose was increased to 250mg twice a day (BD) (Group 2). If the response still remained below 50% after 3 weeks of BD, the patients were treated with itraconazole (ITR)(Group 3). Trichophyton interdigitale was confirmed on all 64 isolates obtained on culture. Forty four (68.7%) isolates had high (≥1 μg/ml) MICs to TRB. Six isolates were found to have aminoacid substitution Leu393Phe in SQLE protein, while one had the substitution Phe397Leu. The difference in modal MICs to TRB between the 3 clinical response groups (1.5157μg/ml, 5.0396 μg/ml and 20.1587μg/ml respectively for group 1,2 and 3) was highly significant. Clinical response was achieved in 68% of those resistant by MIC data, and 42.8% of SQLE mutation harboring isolates, by increasing drug (TRB) exposure.We infer that TRB resistance in dermatophytes has reached alarming proportions in our patients. Though improved outcomes were achieved with higher drug exposure, with the high failure rate seen in the study, the case for shifting to another class of antifungals as first line agent against dermatophytoses is strong.

Introduction: Lead (Pb) is a transition metal and a known male reproductive toxicant that induces its effects mainly through oxidative stress. This study investigated the effects of L-Citrulline (Cit) supplement on reproductive functions and antioxidant activities in Lead acetate treated male rats. Materials and Methods: Twenty  male rats (180-200 g) were grouped into four  and treated as follows; Group 1 (Control), given distilled water, Group 2 was given Pb acetate (2.25mg/kg), Group 3 was co-treated with Pb acetate (2.25mg/kg) and Cit (900mg/kg) and Group 4 was given Cit (900mg/kg) only. All administrations were done orally for thirty days. Caudal sperm, serum hormone levels and testicular antioxidant activities and Nitric oxide levels were evaluated at the end administrations. Results: Results showed decrease (p<0.05) in sperm morphology, count, viability, motility, FSH, LH, Testosterone, Catalase, Nitric Oxide and Super oxide dismutase in Group 2(Pb treated rats), when compared to Group 1(Control).However, in Group 3 (Pb acetate co-administered with Cit) the effect was significantly reversed (p<0.05) compared with Group 2 and significant increase was observed in Group 4 (Cit only group) compared with Group 2. There was an increase (p<0.05) in Malondialdehyde level in Group 2 compared with (Group 1) Control while a significant decrease (p<0.05) was observed in Groups 3 and 4 compared with Group 2. Conclusion: The results of this study suggest that L- Citrulline supplement has ameliorating capacity on the toxic effect of Lead acetate on sperm parameters.

This study aimed to find out the parasitemia of DDY white mice infected with T. evansi of Pidie and Pemalang isolates obtained from Bbalitvet Bogor. A total of 12 mice were divided into 3 treatment groups. Group 1 (K1) without any treatment, group 2 (K2) was inoculated with 104 T. evansi Pidie isolate, and group 3 (K3) was inoculated with 104 T. evansi Pemalang isolate. Parasitemia examination was carried out every two days and the level of parasitemia was observed as well. Parasitemia examination was conducted until all mice died. Parasitemia of mice infected with Pidie isolate was characterized by rapid rise of parasitemia in blood (107-108/mL of blood) in a short time (2-4 days) since first parasitemia was detected and followed by death at day 4. The parasitemia of mice infected with Pemalang isolate increased in the blood (108-109/mL of blood) on day 4 and maintained for a few more days and then fluctuated for a few more days before the animal was dead. In conclusion, there was the difference in parasitemia level between Pidie and Pemalang isolates. Key words: Trypanosoma evansi, parasitemia, Pidie isolate, Pemalang isolate

Background: Social media has become a source of medical information. Cleft lip and palate is a visible congenital anomaly. The aim of the study was to analyze Instagram® posts on the topic of cleft lip. Methods: Instagram® posts with “#cleftlip” from March 2014–March 2017 were accessed. Separate lists of expressions (hashtags, meaningful words, words with emojis or emojis alone) were prepared for primary posts and for replies. Thirty expressions statistically most frequent in primary versus secondary posts and 30 in secondary versus primary posts were identified (Group 1) as well as 30 English words or hashtags (Group 2), non-English words or hashtags (Group 3) and emojis (Group 4). The frequencies of expressions were compared (Z-test for the difference of two population proportions). Results: There were 34,129 posts, (5427 primary posts and 28,702 replies), containing 62,163 expressions, (35,004 in primary posts). The occurrence of all expressions was 454,162, (225,418 in primary posts and 228,744 in replies). Posts with positive expressions such as “beautiful”, “love”, “cute”, “great”, “awesome” occurred more often than these with negative ones. In replies all emojis were positive. Conclusions: Numerous Instagram® posts referring to cleft lip are published and do provoke discussion. People express their solidarity and sympathize with persons affected by cleft.

Two experiments were conducted to determine if withdrawal of progesterone during the luteal phase of the oestrous cycle affected the ability of the ovine uterus to secrete prostaglandin F2α(PGF2α ) in response to oxytocin. In Experiment 1, 18 ewes were ovariectomized on Day 9 and Day 12 after oestrus. Ewes were subdivided into three treatment groups (n= 6 per group): Group-1 ewes underwent sham surgery; Group-2 ewes received oestradiol (OVX + O); and Group-3 ewes received oestradiol + progesterone (OVX + O,P). Oxytocin was administered to each ewe on Days 10, 13 and 15 after oestrus. Concentrations of 13,14-dihydro-15-keto-PGF2α (PGFM) were determined in samples of jugular venous blood for 2 h after oxytocin challenge. The magnitude of the PGFM response 24 h after ovariectomy was greater (P < 0·1) in ewes from which progesterone had been withdrawn (OVX + O) than in ewes in which progesterone was maintained (intact controls and OVX + O,P). Therefore, progesterone appears to exert an inhibitory effect on uterine secretory responsiveness to oxytocin which is removed by progesterone withdrawal. In Experiment 2, ewes were ovariectomized on Day 11 and assigned to 1 of 4 treatment groups (n = 6 per group): Group 1, no steroid replacement (OVX); Group 2, oestradiol replacement (OVX + O); Group 3, progesterone replacement (OVX + P); or Group 4, progesterone+oestradiol replacement (OVX + O,P). Ewes received oxytocin on Day 12 and Day 15. On Day 12, uterine secretory responsiveness to oxytocin was greatest in ewes in the OVX + O group (P < 0 · 1). Responsiveness was low in ewes in the OVX group, as it was in ewes in both groups that received progesterone replacement. Therefore, the increase in uterine secretory responsiveness to oxytocin following progesterone withdrawal is dependent on oestradiol replacement.
