RESUMO
The current study aimed to investigate the ameliorative effects of Artemisia annua (RA) extract on hepatic toxicity induced by gentamicin injection mice. Sixteen mice were divided into four groups; the control group received saline, the second group received 1% A. annua (RA) extract, third group injected 80 mg/kg gentamicin (GEN) intraperitoneally. The protective group treated with a combination of GEN and A. annua. All mice were treated for consecutive 15 days. Results confirmed that hepatic biomarkers (GPT, GCT, GOT, IL-6 and IL-1ß), all were altered after gentamycin injection. The histological analysis confirmed that gentamycin injected mice showed portal vein congestion, micro and macro steatosis, and nuclear pyknosis of hepatocytes. The protective group showed intact central vein with less microsteatosis of some hepatocytes. Immunochemistry analysis confirmed that the immunoreactivity of COX-2 gene showed negative impact in examined groups. Unlike, NF-κB gene exhibited diffuse positive expression in the gentamicin group. TGF-ß1 immunoreactivity was mild positive in control and highly upregulated in gentamicin treated mice, all were normalized after RA administration. In conclusion, RA showed a beneficial impact against gentamycin induced hepatic toxicity at cellular and biochemical levels by regulating proteins and inflammatory markers associated with liver activity.
RESUMO
CT scanning deliver much higher radiation doses than planar radiological procedures, which puts patients to high risks. This study measures and evaluates patient doses during chest and abdomen computed tomography procedures. Particular attention is given to measuring the dose to the equivalent breast (mSv) and to estimate the associated risks of breast cancer to young female patients (15-35 years). Data was obtained from standard examinations from three hospitals. The measured values of CT dose indexes, CTDI (mGy) as well as exposure-related parameters were used for assessment. Breast and effective doses were extrapolated using a software. The results showed remarkable variations of the mean organ equivalent doses for similar CT examinations in the studied hospitals. This could be attributed to the variation in CT scanning imaging technique, and clinical indications. The average effective dose to the chest was 7.9 mSv (2.3-47.0 mSv) and for the abdomen the mean dose was 6.6 mSv, ranging from (3.3-27 mSv). The breast received equivalent doses from chest and abdomen procedures as follows: 10.2 (1.6-33 mSv) and 10.1(2.3-19 mS) Sv respectively. Each procedure yielded high risks of breast cancer for young females. Implementation of accurate referral criteria is recommended to avoid unnecessary breast radiation exposure.

BACKGROUND: Infertility is a global health issue and hysterosalpingography (HSG) is a valuable radiological tool in infertility workup and remains a main modality for investigating female infertility. However, the HSG findings of infertility are not the same worldwide.This study aimed at evaluating the incidence of HSG findings in patients investigated for primary and secondary infertility, correlating these findings with their clinical data that reflect the infertility causes and comparing the findings with previous international studies. METHODS: A prospective descriptive study of 75 female patients referred, as cases of infertility, for HSG examination in Elrebat Hospital and Khartoum Advanced Diagnostic Center. HSG was performed in the first half of the cycle. The procedure and its complications, were explained to the patients and informed consents were obtained. Patients with active pelvic infection and active uterine or vaginal bleeding were excluded from the study. Using aseptic technique and with proper patient's positioning, iodinated contrast was introduced into the cervix under fluoroscopic monitoring, to demonstrate the uterine cavity, fallopian tubes and free spillage into the peritoneal cavity. Personal data, clinical data and HSG findings were analyzed using SPSS version 23. RESULTS: The commonest age group seen was 26-36 years. Close incidences of primary and secondary infertility were detected. 52.7% had abnormal findings in HSG. Tubal pathology (42.7%) being the most common abnormality, followed by uterine and combined abnormalities. There was strong association between past medical history suggesting pelvic inflammatory disease (PID) or past history suggesting tubal blockage secondary to abdominopelvic surgery and tubal abnormalities. CONCLUSION: HSG examinations revealed that the most common abnormality was tubal blockage possibly complicating PID and abdominopelvic surgeries. This reflects the HSG diagnostic and therapeutic role in the assessment of female infertility and the further needs for more preventive measures targeting the reduction of tubal pathologies in developing countries.
