Our study aimed to determine the hospital frequency of hemorrhoidal disease, to identify the contributing factors, describe the clinical and therapeutic aspects and analyze the surgical consequences. We collected 73 patients with an average age of 37.8 years (range: 19 years and 77 years) with a sex ratio of 2.5 in favor of men. We operated on 49 patients or 67.1% of cases. 71.2% of our patients were married and lived in Bamako. Schoolchildren and middle managers made up 39.8% of cases. 82.2% of patients were seen in ordinary consultation and 69.9% complained of progressive anal pain in 66.7% of cases. This pain was triggered by defecation in 88.2% of our patients. The contributing factors were dominated by constipation (53.4%), working in a seated position (41.1%) and a sedentary lifestyle (16.4%) of cases. Stage IV external hemorrhoids and hemorrhoidal thrombosis represented 53.8% of surgical indications. The most used surgical technique was that of Milligan-Morgan, i.e. 51.9% of cases and 45.2% of patients treated medically received a combination of transit regulator, venotonics and analgesics. The surgical aftermath was marked by hemorrhage (3 cases), delayed healing (5 cases), urinary retention (1 case) and scarring anal stenosis (1 case). The morbidity rate was 5.48% of cases and a zero mortality rate. The average length of hospitalization was 2 days with extremes of 1 and 5 days.展开更多

This work aimed to study inguinal hernia in children in the general surgery department of the Reference Health Center of Commune I of the Bamako District;to determine the frequency of inguinal hernia;describe the epidemiological, clinical and therapeutic aspects of inguinal hernias and in order to evaluate the cost of treatment. This was a prospective study from April 2017 to March 2018 during which 60 children with an inguinal hernia were collected. Inguinal hernias in children represented 9.23% of patients operated on in the department. The average age was 59.23 months with extremes of one month and 180 months and a standard deviation of 49.23 years. The male sex was dominant with a sex ratio equal to 9:1. The notion of prematurity was found in 11.7% and was associated with a testicle not in place in 1.7% of cases. 41.7% of our patients were referred by a doctor and 66.7% of patients presented with painless, intermittent inguino-scrotal swelling (83.3% of cases). The hernia was discovered before one week of life in 50% of cases. Inguinal swelling was absent in 11.7% but observed intraoperatively. The inguinal hernia was unilateral in 91.7% of cases and 70% of hernias were discovered by the parents during pushing efforts. The inguinal hernia was located on the right in 61.7% of cases. The hernia swelling was soft, painless, impulsive and reducible in 78.3% of cases. The swelling was inguino-scrotal in 58.3% of cases. The hernia was simple in 95% of patients and hernial strangulation was observed in 3 cases or 5% of cases. 98.3% of patients were ASA I. The treatment was carried out openly in all our patients including closure of the vaginal peritoneal canal in 95% of cases under general anesthesia in 98.3% of cases. The morbidity rate was 8.4% (surgical site infection: 6.7% of cases and hematoma: 1.7%). The immediate consequences were simple in 96.6% of cases. No cases of recurrence occurred during the 6 months after the intervention. The average cost of care was estimated at 69,743 FCFA.展开更多

Stomatal response to elevated CO2 concentrations was examined by stomatal conductance (gs), ratio of intercellular to ambient CO2 concentration (ci/ca) and stomatal number. Reciprocal transfer experiments of stomatal conductance showed that stomatal conductance in high-[CO2]-grown plants increased in comparison with ambient-[CO2]-grown plants when measured at their respective growth CO2 concentration and at the same measurement CO2 concentration (except a reduction in 700 μmol·mol-1 CO2 grown plants compared with plants on unchambered field when measured at growth CO2 concentration and 350 μmol·mol-1CO2). High-[CO2]-grown plants exhibited lower ci/ca ratios than ambient-[CO2]-grown plants when measured at their respective growth CO2 concentration. However, ci/ca ratios increased for plants grown in high CO2 concentrations compared with control plants when measured at the same CO2 concentration. There was no significant difference in stomatal number per unit long needle between elevated and ambient CO2. However, elevated CO2 concentrations reduced the total stomatal number of whole needle by the decline of stomatal line and changed the allocation pattern of stomata between upper and lower surface of needle.展开更多

Two apo C I cDNA clones were obtained. The longer one consistsof 380 nucleotides, including 21 bp and 95 bp at the 5’ and 3’ end of the non translated regions respectively, and a 264 bp fragment in an open reading frame encoding 88 amino acids prepropeptide which contains 26 amino acids of signal peptide and a mature protein (62 amino acids). Comparing the amino acid sequence deduced from this cDNA with those of the published mammalian apo C Is reveals that it shared some structural similarity with rat, mouse and dog apo C I, but it had 5 more amino acids than that of human and baboon. The expression of apo C I mRNA in 8 different tissues were also assayed with Northern blot. The results demonstrated that liver had the highest expression, intestine had much less expression and no expression in other tissues, which is much different from human and other species. This study has laid down a good foundation for further studying on the function and the stucture of tree shrew apo C I gene.展开更多

I. disperse orange 25 （azo type） in supercritieal CO2 were carried out with a high-pressure dyeing apparatus at temperatures from 80 to 130℃ and pressure up to 31 MPa. The effect of operating conditions on color yield （K/S） was investigated in SFD experiment, and the optimum operating conditions for the above two disperse dyes were obtained as follows： the temperature 120℃, the pressure 25 MPa and the dyeing time 100 min. As compared with SFD, the conventional water dyeing （CWD） was carried out with the same dyes and textile. The results show that the better fastness, levelness and apparent color can be achieved in SFD and the SFD process has many significant advantages over the CWD process.展开更多
