RESUMEN
Chronic suppurative otitis media (CSOM) is a notorious infection in developing countries causing serious local damage and threatening complications. It was a cross sectional observational study to isolate and identify aerobic bacteria and to analyze the susceptibility pattern of the aerobic bacterial isolates. It was carried out from March 2017 to July 2018 in the department of Microbiology, Mymensingh Medical College, Mymensingh, Bangladesh. Samples were collected from Outpatient of ENT department, MMCH. Out of a total 300 patients with CSOM were enrolled in this study and 209 were culture positive. Among them gram negative organisms were 129(61.72%) and gram positive organisms were 70(33.49%). The most frequently isolated organism in this study was Pseudomonas aeruginosa 72(34.44%), gram positive organisms S. aureus 63(30.14%), E. coli 21(10.04%), other Pseudomonas spp (other than P. aeruginosa) 15(7.17%), mixed bacterial infectios 10(4.78%), Proteus spp 9(4.30%), CoNS 7(3.34%), Klebsiela lspp 7(3.34%), Acinetobactor spp 5(2.39%). P. aeruginosa isolates had least resistant to imipenem and colistin, S. aureus were showed high sensitivity to Vancomycin and Linezolid and E. coli were sensitive to imipenem and amikacin, ciprofloxacin and amikacin respectively. Pseudomonas aeruginosa was the most common bacteria isolated from chronic discharging ears followed by Staphylococcus aureus. Piperacillin-Tazobactum, Ciprofioxacin, Gentamicin and Amikacin were found to be the most suitable drug for Pseudomonas aeruginosa, S. aureus and E. coli. The resistance against ceftriaxone and aztreonam was found to be very high.

AIM: This study evaluated changes in immunoendocrine makers over an international series in professional rugby union players (N.=8). METHODS: Venous bloods were taken on camp-entry, as well as before and after (0, 14 and 38 h) two games spaced over 21-days. Samples were analysed for changes in serum C-reactive protein (CRP), cortisol (C), testosterone (T), blood leukocytes, interleukin 6 (IL-6) and creatine kinase (CK). RESULTS: Significant reductions in CK activity and CRP concentrations were evident on day 5 (pre-game 1) when compared to camp-entry (day 1); P<0.05. A large acute-phase response was observed following both games. Differences in the magnitude of this response appeared dependant on the number of collisions players experienced during play. Compared to camp-entry, sharp increases in C (40%) and decreases (37%) in T were evident after both games; P<0.05. A gradual increase in T/C ratio was observed throughout the tournament; values 35% and 45% higher on days 19 and 21 than those observed at camp-entry (P<0.05). CONCLUSION: Current data suggests that improved physiological recovery can be achieved during an international rugby union series. Monitoring of previous club activity is essential to ensure optimal player readiness prior to participation in international rugby union games.

Seasonal variation of the coloration of the testes due to the presence of melanin pigments was observed in a wild passerine bird Dicrurus adsimillis. The proportion of melanin in the testes is highest in the recrudescence period, when the lipid content is moderate and cholesterol is present in the tissue in trace amounts. In the reproductive period, when lipids are depleted, the melanin content is very low; in this stage, cholesterol is stored in the tissue in large amounts. During the post-reproductive period, melanin pigment and lipids both fall almost to zero level and only traces of cholesterol are to be found. In the recrudescence phase, the amount of all three (i.e. melanin pigment, tissue lipids and cholesterol) rapidly increases. The probable correlation between melanogenesis in testicular tissue and hormones and their lipoid precursors is discussed.

The similar structure hypothesis was tested by comparing the performance of mentally retarded adults and their nonretarded mental age peers on a series of Piagetian tasks. We controlled for variables that influence the testing of mentally retarded subjects and performance on Piagetian tasks. Statistical analysis revealed that five tests favored the developmental position whereas two tests favored the difference position. Qualitative analysis provided reason to question the validity of two of the seven tests. Nevertheless, the evidence still favored the developmental position 4:1. Corollaries challenged the use of vocabulary tests for matching and raised a caveat concerning the acquisition by mentally retarded adults of key concrete operations skills.

The mast cell population has been studied during early decidualization of the mouse uterus. The number increases in early pregnancy until the attachment phase when a sharp depletion is noticed. This fall has been correlated with stimuli of maternal origin, but at the same time the presence of a blastocyst at the presumptive implantation sites seems to exert a significant effect on the depletion of mast cells. A relationship between the number of mast cells in the uterus and the physiological state of the organ has definitely been established [Harvey, 1964; Likar and Likar, 1964; Gibbons and Chang, 1972; Brandon and Evans, 1983]. The number of mast cells in the pregnant uterus is known to decrease around the time of implantation in the rat [Shelesnyak, 1960; De Feo, 1967; Brandon and Bibby, 1979]. Several workers believe that the mast cell population and histamine content decrease as a result of a rise in circulating estrogen [Westin, 1955; Gibbons and Chang, 1972; Spaziani, 1975]. In the present communication the possibility of a relationship between the decrease in mast cell population and the presence of a blastocyst, whose estrogenic role has been reported [Dickmann and Dey, 1973; Dickmann et al., 1975; Sengupta et al., 1977], in the uterine horn has been discussed.
