Perineal trauma is a non-surgical solution of continuity of posterior perineal committing under the effect of a violent exertion during childbirth. It occurs at the time of disengagement, either from the head or the posterior shoulder. Objectives: To calculate the perinea trauma during childbirth, describe the socio demographic profile of the women in childbed, identify contributory effects and appreciate the maternal prognostic. Methodology: It was a prospective study, descriptive type of 6 months (from May 19 to November 20, 2014). It took place at the maternity ward of Donka National Hospital. It concerned all received parturient, women in bed of a single fetus in the unit and having had a perineum traumatism. The real ones were epidemiologic, therapeutic clinical and prognostic. Results: We have recorded 110 perinea traumatism cases over 3496 childbirth let say a frequency of 3%. The socio demographic profile of the woman who did perinea traumatism was a teenager (42.7%), professional occupation (29.1%), married (88.2%), schooled, secondary and Technical level (42.7%), primary (70%) having had more than 3 prenatal consultations (73.6%). Contributory effects were: prim parity, young age, instrumental extraction by obstetrical forceps and the fetal weight between 2500 to 3999 g. Surgical management was (100%). The following were simple in 88.2% cases versus 11. 8% of complications. Conclusion: The reduction of this frequency requests systematical practice and corrects recentered prenatal consultations and the respect of episiotomy indications.

The inability of cultured primary Leydig cells to maintain luteinizing hormone(LH)-responsive testosterone formation in vitro for more than 3-5 days has presented a major challenge in testing the effects of trophic regulatory factors or chronic exposure to environmental toxicants on these critically important *** the present study, our major objective was to establish culture conditions sufficient to maintain LH-responsive testosterone formation for up to a month. The formula contains a mixture of DMEM/F12 and M199 culture medium, containing insulin(10 ug/ml), PDGFAA(10 ng/ml), lipoprotein(0.1 mg/ml), horse serum(1%) and a submaximal amount of LH(0.2 ng/ml). Under this culture condition, adult rat Leydig cells can be maintained in vitro for up to 4 weeks, with littledivision, but retained the ability to respond to LH stimulation and to produce testosterone. As a prove-principle purpose, we have used the culture system tested the chronic effect of a common environmental-relavent compound, MEHP, on Leydig cell testosterone production. The results indicated that while MEHP, at the concentration of 1 uM, did not affect Leydig cell steroidogenesis acutely when incubated with the cells for 24 hours, it indeed significantly inhibited T production when the cells were exposed to the compound for two weeks. The results suggest that the new culture condition we have established is useful to screen and test the potential chronic effects of environmental toxins on Leydig cells.

Cowpea yield improvement is done by adding agricultural inputs. The use of natural substances as pesticides is being encouraged to fight against cowpea field pests. The pesticidal potentials of Azadirachta indica and boswellia dalzielii water extracts, Metarhizium anisopliae, alone and in combination with plant extracts, and a commercial synthetic pesticide (Decis®) were tested in field on two varieties of cowpeas, Vigna unguiculata in two agroecological zones (Guinean Savanah and Sahelian Savanah) of Cameroon. The field trials were carried out in a full randomized block design including nine treatments and a control. Four replications were made concerning the different treatments and control. At the flowering stage, the cowpea field was sprayed three times with different pesticidal formulations at the interval of five days. The number of ramifications per plant, and that of pods per block and seed yield were determined. The pesticide formulations considerably (p ®). bafia variety treated with the combination of M. anisopliae and A. indica recorded the highest ramification rate (37.03 ± 1.59) in Maroua (Sahelian Savanah). The same variety also produced more important pods number (90.50 ± 16.66) in Ngaoundere (Guinean Savanah) with the binary combination of two plants used in this experiment. The highest seed yield (44.23 ± 2.31) was recorded in Ngaoundere with b125 variety treated with the combination of the three pesticidal formulations separately (A. indica, b. dalzielii, M. anisopliae). The plant products used in this work, M. anisopliae and their mixtures could supersede the synthetic pesticides considering environmental issue in cowpea crop protection. Then, such formulations would not only improve crop productivity but also preserve environment from the pollution due to the use of synthetic residual chemicals.

通过引入特征温度与硫系玻璃相匹配的高性能热塑性聚合物聚酰亚胺（PEI）作为光纤包层,结合复丝工艺制备了像素数为900的As2S3/PEI光纤传像束,表征了光纤的损耗、光纤束的断丝率、分辨率和串扰率。As2S3/PEI光纤在2~6μm波段传输性能优异,背景损耗约为0.5 d b/m,在S-H杂质对应的4.0μm波长的峰值损耗为3.5 d b/m。单丝直径为80μm、像素数为900的光纤束的断丝率为1%,分辨率为7 line/mm,串扰率为1%,通过此传像束得到了清晰的电烙铁红外图像。而且,将PEI溶于二甲基乙酰胺（DMAC）后使光纤束表现出很好的柔性。采用这种类似＂酸溶玻璃＂的可溶于特定溶剂的热塑性聚合物,作为过渡介质,结合复丝工艺有望制备出柔性高分辨率硫系玻璃光纤传像束。

Introduction: Orthostatic Hypotension (OH) is a frequent situation during consultation in hypertensive patients. The prevalence in the general population increases with age and it is recommended to systematically search for it in patients with multiple comorbidities. The objective of this study was to determine the prevalence of orthostatic hypotension;describe their socio- demographic profile, the various clinical and paraclinical aspects and the predisposing factors of orthostatic hypotension in treated hypertensives, controlled or not. Method: This was a descriptive cross-sectional study, from January 2 to June 30, 2022 in the cardiology department of the Ignace Deen National Hospital. Included in this study were all patients who presented with orthostatic hypotension under antihypertensive treatment, regardless of age and sex, and who agreed to participate in the study. The non-inclusion criteria were hypertensive patients without OH and those who had not agreed to participate in the study. Each patient had blood pressure and heart rate measured in the supine position at room temperature and with an empty bladder. Then the measurement is taken again three (3) minutes after the switch to orthostatism. We retained the diagnosis of OH if the SbP drops by at least 20 mmHg and/or the PAD by at least 10 mmHg three (3) min after the transition to orthostatism. Our data obtained were analyzed in the Epi-info 7.4.0 software. Results: During our study period, we investigated 385 presented with OH, 12.2%. The mean age of the patients was 60.83 years ± 10.01 years and hypertensive patients, 47 of whom the M/F sex ratio was 0.81. In our study, blood pressure was not controlled in 36.2% of our patients with a predominance of grade 3 hypertension, a rate of 55.32%. Renal failure, anemia, heart failure and stroke were the main comorbidities associated with the occurrence of HO. The most incriminated factors were age with a frequency of 74.47%, followed by obesity at 44.68% and
