Background: Cisplatin is a potent antineoplastic agent widely used for a variety of malignancies. However, it has many dose-limiting side effects such as neurotoxicity, cytotoxicity and ototoxicity. The aim of our study was to determine the effectiveness of astaxanthin (ASX) as a cytoprotective agent against cisplatin-induced cytotoxicity in the submandibular glands of rats.Methods: Thirty-six adult male Wistar albino rats were divided into six groups as follows: group I: saline control; group II: 75 mg/kg/day ASX; group III: 16 mg/kg cisplatin; group IV: 25 mg/kg/day ASX + cisplatin; group V: 75 mg/kg/day ASX + cisplatin; group VI: olive oil + cisplatin. In all groups, submandibular gland histopathological and histochemical investigations were done using a light microscope. Every rat section was semi-quantitatively scored. Neutrophil infiltration density, myoepithelial cell density in the degeneration area, degenerative granular duct cell density, degenerative seromucous acinus cell density, and changes in the content of the secretory granules of seromucous acini and granular ducts of the parenchyma and stroma were calculated.Results: The results of the analysis of the mean acinus area of the submandibular gland revealed that there was a significant decrease in cisplatin group rats when compared to control rats (p<0.05, p=0.00). However, there was no significant difference between-group IV, V and control group in terms of mean acinus area. (p=0.541, p=0.773). The results of the analysis of the mean ducts area of the submandibular gland also showed that there were significant increased group III compared to control rats (p<0.05, p=0.031). There was no significant difference between-group IV, V and control group in terms of mean ducts area (p>0.05, p=0.921). Similarities were observed in the mean ducts area with the group IV and the group V (p>0.05, p=0.571).Conclusions: These results suggest the possibility that the clinical use of ASX could reduce or prevent damage to the salivary gland of patients receiving cisplatin chemotherapy.

ABSTRACT Aim The purpose of this study was to evaluate the fracture strength of roots instrumented with the self-adjusting file (SAF; ReDent-Nova, Ra'anana, Israel) and the Reciproc reciprocating file and that were and were not obturated using the warm vertical lateral compaction technique. Materials and methods In total, 75 mandibular premolar teeth were sectioned at or below the cementoenamel junction to obtain roots 13 mm in length. The roots were balanced with respect to buccolingual and mesiodistal diameters and weight. They were distributed into four experimental groups and one control group (n = 15): No instrumentation (group I), instrumentation with SAF files but no obturation (group II), instrumentation with SAF files and obturated with warm vertical lateral compaction (group III), instrumentation with Reciproc File but no obturation (group IV), and instrumentation with Reciproc File and obturated with warm vertical lateral compaction (group V). AH Plus sealer (Dentsply DeTrey, Konstanz, Germany) was used along with gutta-percha points. One week later, a vertical load was applied to the specimen's canal until fracture occurred. Data were statistically analyzed using one-way analysis of variance (p = 0.05). Results The mean fracture load was 312.83 N for group I, 297.35 N for group II, 359.15 N for group III, 231.51 N for group IV, and 275.81 N for group V. Conclusion The fracture resistances exhibited a statistically significant difference between all the groups. Teeth instrumented by SAF exhibited a better fracture resistance.

The aim of the study was to investigate for the effect of different drugs immediately after parturition on the reduction of retention of placenta in selected cows. One hundred pregnant cows from members of Community Based Dairy Veterinary Foundation, Shikalbaha, Potiya, Chittagong were included in this study belonged to two breeds viz, cross bred and local, aged 3-8 years, calved 1-5 times with BCS 2-3.5. The cows were divided into five groups; group L (n=20) treated with oxytocin 50 iu/intramuscular, group IL (n=20) treated with calcium 400 ml/intravenous, group III: (n=20) treated with methyl ergometrine maleate 20 mg/intramuscular, group IV: (n=20) treated with oxytocin 50 iu/ intramuscular plus calcium 400 ml/ intravenous and group V: (n=20) served as non-treated control. The incidence of retained fetal membrane was 35% in control group, while that of pooled treatment group had 15%. This reduction was significant (P<0.05). In the present study, there was no significant difference among the different treatment groups on the prevention of retention (P>0.05). The incidence of retained fetal membrane was affected by the age and breed of cows (P<0.05). However, this effect was override by treatment and injection of drugs immediately after parturition decreases the incidence of retention of placenta in cows.

The purpose of our study is to determine the correlation between the effects of smoking, triglycerides and cholesterol (total, HDL, LDL) and periodontal disease. 90 patients, smokers diagnosed with periodontal disease and 30 nonsmoker patients (control group), in the age of 30-60 years, were studied. Patients were divided into 4 groups, each of 30 patients as follows: group I - smokers up to 10 cigarettes a day, group II-smokers between 10-20 cigarettes a day, group III-over 20 cigarettes a day, group IV- control group, nonsmokers. The values of the Silness-Loe dental plaque index (DPI), the gingival bleeding index (GI), the Periodontal Disease Index (PDI) -Ramfjord were noted in both the examined and control groups. The values of total cholesterol and HDL cholesterol showed statistically significant difference between the mean values �in the examined groups, while mean values �of HDL cholesterol in the second and third examined subgroups and control group were in higher range than the normal one. We concluded also that there is a relationship between smoking, the number of cigarettes smoked and the periodontal disease.

Previous research has examined the utilisation of musical cues to improve the performance of cardiopulmonary resuscitation (CPR) delivered in training environments. We postulated a musical cue that is both contemporary and transcends cultures may improve CPR performance. Our aim was to establish whether chest compressions are performed with improved rate and depth if a song of a fixed beat (PinkFong’s ‘Baby Shark’ with a tempo of 115 beats per minute (bpm) and 15 beats in each verse) is played to a healthcare professional immediately before undertaking CPR compared to whale noises (a non-metronomic rhythm). 58 Participants of a paediatric conference (majority doctors) were randomly assigned to listen to a minute of Baby Shark (28) or whale song (30) and then undertake a minute of CPR. There was no significant difference in the mean compression rate between the Baby Shark and control groups, with the groups achieving 121 and 125 bpm, respectively (p=0.18). In relation to compression depth within the target zone, the Baby Shark group had more compressions completed within the target zone (55%) than the control group (39%) although this difference was not significant (p=0.08). Listening to Baby Shark prior to undertaking simulated CPR does not improve overall performance, but there is a potential tendency to improve adequate compression depth which may be beneficial in training exercises.

Pyrethroid cyhalothrin (PC) is an insecticide that is used worldwide for pest control in agriculture and household use. Samoa extract (SE) is a potent antioxidant protecting cells from oxidative stress. The present study investigates the protective and therapeutic effect of SE on PC-induced changes in sperm quality in male rats. Fifty adult male albino rats were divided into five groups: group I: served as control; group II: received PC i.p. only (6.2 mg/kg b.wt.); group III: received SE only (100 mg/kg b.wt., p.o.) for eight weeks; group IV: received SE as a protective agent daily for eight weeks, then followed by the administration of PC (i.p.) three times a week for two weeks; group V: exposed to PC (i.p.) three times a week for two weeks, then treated with the SE daily for 8 weeks. Results showed that PC caused markedly impaired sperm quality (a count, viability, motility, and abnormality). Compared to PC-treated animals, SE in the protective group markedly restored the alteration of sperm indices. However, SE in the curative group was found to be less effective in restoring PC-induced alterations. In conclusion, the data of this study revealed that the SE as a protective agent is more effective than as a therapeutic agent. Keywords: Samoa; Pyrethroid; Sperm quality; Rat

INTRODUCTION We observed that a number of patients presenting to our clinic with diverticular fistulation were taking nicorandil for angna. Recognised side effects of nicorandil include gastrointestinal and genital ulceration. The aim of our study was to determine whether nicorandil is an aetiological agent in diverticular fistulation. PATIENTS AND METHODS We conducted a case-control study of patients with diverticular disease related enteric fistulae. Two patient groups were identified: a study group of patients with diverticular fistulae, and a control group with uncomplicated diverticular disease. The proportion of patients who had ever used nicorandil was compared between the two groups. RESULTS A total of 153 case notes were analysed, 69 patients with fistulae and 84 control patients with uncomplicated diverticular disease. Female to male ratio in both groups was 2:1. The mean age was 71 years in the fistula group and 69 years in the control diverticular disease group (P = ns). Of those with colonic fistulae, 16% were taking nicorandil compared with 2% of the control group (odds ratio 7.8; 95% confidence interval 1.5–39.1; P = 0.008). There was no significant difference in rates of ischaemic heart disease between fistula and control groups. CONCLUSIONS Nicorandil is associated with fistula formation in diverticular disease.
