Kanker payudara adalah tumor ganas yang terbentuk dari sel-sel payudara yang tumbuh dan berkembang tanpa terkendali sehingga dapat menyebar ke jaringan atau organ yang berada dekat dengan payudara atau ke bagian tubuh lainnya. Annona muricata Linn atau Graviola telah digunakan sebagai obat tradisional untuk menangani berbagai jenis penyakit seperti demam, rematik, kanker dan juga sebagai sedatif, insektisida dan imunosupresif. Pada penelitian ini, cell line kanker payudara MCF-7 diberi ekstrak etanol A. muricata kemudian diinkubasi 24 jam. Setelah itu dilakukan uji sitotoksik menggunakan metode MTT assay. Parameter yang digunakan pada uji sitotoksik adalah IC50 yang menunjukkan konsentrasi inhibisi sel kanker sebanyak 50% dengan nilai IC50 sebesar 117,87 μg/ml. Ekstrak dapat dikatakan memiliki aktivitas sitotoksik jika nilai IC50 kurang dari 1000 μg/ml setelah 24 jam kontak dengan sel kanker. Dengan demikian, dapat disimpulkan bahwa ekstrak etanol daun A. muricata dapat digunakan sebagai pilihan terapi anti-kanker alami untuk kanker payudara.Kata Kunci:  Kanker payudara, Ekstrak etanol daun Annona muricata, MCF-7, MTT assay

Reperforation after gastric perforation repair is a complication which increases the rate of morbidity and mortality in gastric perforation. The lack of ability of the tissue to use oxygen in septic condition causes anaerobic cellular metabolism and furthermore it will cause failure in closing the perforation. The production of anaerobic metabolism is lactic acid which can be measured from the blood. The aim of this study is to determine the cut-off point of blood lactate level as a predictor of reperforation after repairing gastric perforation. Forty-six patients diagnosed as gastric perforation, who were repaired in Dr Soetomo Hospital from October 2014 to October 2015 were recruited as samples. Serum lactate was taken one hour before repairing the perforation. After being repaired, the patients were observed until the 14th day to evaluate whether any reperforation would occur or not . The design of this research was cross-sectional, analytic observational. The data was analyzed using independent t-test and ROC for obtaining the cut-off point as a predictor of the reperforation after the gastric perforation was repaired. There was a significant difference in the mean of lactate level in the group with reperforation compared with that of the non-reperforation group, that is as big as 3.74±0.59 mmol/L and 2.60±0.76 mmol/L. Using ROC curve analysis, there was the cut-off point of lactate level for reperforation 3.35 mmol/L, with sensitivity 92.9%, specificity 84.4%, positive predictive value 72% and negative predictive Value 96.4%, accuracy 87.0% and in the AUC value 0.902.

Generalized peritonitis caused by spontaneous gall bladder perforation is rare and difficult to diagnose preoperatively. The increased absorption of the spilling conjugated bile from the gall bladder by the inflamed peritoneum causes jaundice and direct hyperbilirubinemia. A 56-year-old male patient with septic generalized peritonitis and obstructive-type hyperbilirubinemia came to our hospital. The blood examination showed that total, direct, and indirect bilirubin were 6.20, 5.38, and 0.82 mg/dl. The gall bladder perforation was not detected on USG, CT scan, and MRCP. On laparotomy, we found a 0.5 cm perforation on the fundus of the gall bladder and 2500 cc of bilious fluid in the peritoneal cavity. Cholecystectomy was performed, and the patient completely recovered after the surgery. Preoperative diagnosis of spontaneous gall bladder perforation is difficult even by using ultrasonography, CT scan, and MRCP. The inflammatory reaction of the peritoneum in bile peritonitis increases the absorption of the spilled conjugated bile from the peritoneal cavity. The obstructive-type hyperbilirubinemia without dilatation of the bile duct on imaging examination was the sign of bile leakage into the peritoneal cavity. In septic condition, the preoperative diagnosis of the spontaneous gall bladder perforation is important to establish so that the surgeon can make only a minimal procedure in reducing the morbidity. Therefore, it could be concluded that the presently occurring obstructive-type jaundice without dilatation of the bile duct in the case of generalized peritonitis is a specific sign of spontaneous gall bladder perforation.

Surgical management in obstructive jaundice still contributes to significant morbidity and mortality. One of complications following surgery in obstructive jaundice is sepsis. This complication is caused by the toxic effects of bilirubin and bile salts, endotoxins, bacterial translocation, modulation of the immune-inflammatory cascade, decreased cellular immunity and/or nutritional status. Many studies have shown the elevated inflammatory response indicator, interleukin-1 (IL-1b), in patients with obstructive jaundice. However, only a few report described the association between the indicators of obstructive jaundice (alkaline phosphatase [ALP], g-glutamyl transpeptidase [GGT], and bilirubin) and the indicator of inflammatory response ). This study aimed to investigate the association between the indicator of obstructive jaundice (ALP, GGT, and bilirubin) and the level of interleukin-1b (IL-1b) in dogs as the animal model. We performed ligation on distal common bile ducts (CBD) to produce a model of obstructive jaundice. Every three days within a month, the blood samples from ten dogs were extracted to determine the ALP, GGT, direct and total bilirubin, and IL-1b levels. We found a significant correlation between the ALP and GGT with IL-1b level with p-value of 0.036 (r=0.626) and 0.003 (r=0.826). However, there was no association between the increased direct bilirubin with the IL-1b level (p=0.068; r=0.537). Moreover, the increased level of ALP and GGT had a strong correlation with the increased level of direct bilirubin with p-value of 0.004 (r=0.810) and p=0.011 (r=0.746). In conclusion, the increased level of GGT was the strongest indicator for inflammatory response in dogs with obstructive jaundice. Furthermore, the increased levels of GGT and ALP might imply the development of obstructive jaundice in dogs.
