Histone deacetylases (HDACs) inhibition causes hyperacetylation of histones leading to growth arrest, differentiation and apoptosis of tumor cells, representing a new strategy in cancer therapy. Many of previously reported HDACs inhibitors are hydroxamic acid derivatives, which could chelate the zinc ion in the active site in a bidentate fashion. However, hydroxamic acids occasionally have produced problems such as poor pharmacokinetics, severe toxicity and low selectivity. Herein we describe the identification of a new series of non-hydroxamate HDACs inhibitors bearing diketo ester moieties as zinc binding group. HDACs inhibition assay and antiproliferation assays in vitro against multiple cancer cell lines were used for evaluation. These compounds displayed low antiproliferative activity against solid tumor cells, while good antiproliferative activity against human leukemic monocyte lymphoma cell line U937. Compound CPUYS707 is the best with GI50 value of 0.31 micromol x L(-1) against U937 cells, which is more potent than SAHA and MS-275. HDACs inhibition activity of these compounds is lower than that expected, further evaluation is needed.

Though the occurrence of multiple primary malignant tumor is a rare finding but the reported cases of it has increased in recent years. We collected multiple primary cancer of different organ, tissue and the multicentric origin of bilaterally paired organs. This paper reports 6 cases of multiple primary malignant tumors which were experienced at Yeungnam university hospital in Taegu during the past 2 years with review of journals. The results were as follows. 1. The incidence of multiple primary cancer was 0.31% for 2 years (1987-1988). 2. The ratio between male and female was 1:1 and mean age of incidence was 54.1 years. 3. The ratio between synchronous and metachronous (interval more than 6 months) was 1:1. 4. The time interval between first and second cancer was average 2.7 years in metachronous cases. 5. The most frequent involved organ was stomach, breast and colon in order of frequency. 6. The incidence of familial cancer associations was found in one out of 6 cases. 7. The test of DNCB, multitest CMI and ratio of T4 to T8 were performed in 4 cases but there was no definitive evidence of abnormality. We concluded that every effort should be made to discover the presence of synchronous malignancies in the patients who are being treated for a known tumor, and also special care should be given to detect new metachronous lesions is required.

Authors evaluated the accuracy of preoperative pelvic CT scan staging and its effects on management in 12 biopsy proved rectal cancer patients. Authors also studied postoperative CT in 5 patients to detect disease recurrence and metastasis. Preoperative CT staging was identical to surgical and/or pathological staging in 9 patients (75%), but it was underestimated in two cases and overestimated in one instance than in surgical stagings. In 7 cases, CT scan did not alter original choice of procedures. However, preoperative CT staging gave definitive informations to change management plans in 5 cases otherwise the treatment would be difficult and inadequate. Postoperative CT showed local recurrence in one and liver metastases in 2 cases. One of them was not detected at exploratory laparotomy.

BACKGROUND: The laparoscopic cholecystectomy (LC) has been accepted as the procedure of choice for chronic cholecystitis. However in cases of acute cholecystitis, the safety and the efficacy of LC has not been fully determined. Thus we performed this study to assess the clinical outcomes of a LC for acute cholecystitis to evaluate it's efficacy and safety. METHODS: The authors retrospectively analyzed 1,164 LCs performed in Yeungnam University Hospital from May 1991 to March 1996. Among the 1,164 LCs, 118 were performed for acute cholecystitis and 1,046 were performed for chronic cholecystitis. The authors compared the mean operation time, the conversion rate to an open cholecystectomy (OC), the reasons for conversion, the complication rate, the postoperative hospital stay, and the postoperative use of analgesics between the patients with acute cholecystitis and the patients with chronic cholecystitis. RESULTS: In the 1046 patients with chronic cholecystitis, the mean operation time was 55.9 minutes, the conversion rate to an OC was 2.7%, the complication rate was 4.0%, the mean postoperative hospital stay was 3.3 days, and analgesics were used in 48% of the patients. However in the 118 patients with acute cholecystitis, the mean operation time was 65 minutes, the conversion rate to an OC was 11.8%, the complication rate was 16.9%, the mean hospital stay was 4.4 days, and analgesics were used in the 60% of the patients. Also the authors found that the longer duration of preoperative symptoms and an advanced state of inflammation (e.g., GB empyema or gangrenous changes) were the two most common causes of conversion to an OC in the case of acute cholecystitis. Although all the analyzed parameters (especially, the conversion rate and the complication rate) were higher in the patients with acute cholecystitis than they were in the patients with chronic cholecystitis, a LC for acute cholecystitis seems to be acceptable because there were no mortalities and there were no life threatening complications. CONCLUSIONS: From, the aspects of safety and efficacy, a LC can be performed in most patients with acute cholecystitis. However, it should be remembered that the prolonged duration of symptoms prior to a LC increases the conversion rate to O.C. and if we confront the advanced cholecystitis (GB empyem or gangrenous change) with difficult Calot's triangle during a L.C., early conversion to an OC should be considered.

To improve the water solubility of daidzein, solid inclusion complexes of daidzein with two amino-modified β-cyclodextrins (ACDs), i.e., mono-6-amino-6-deoxy-β-cyclodextrin (NCD) and mono-6-ethylenediamino-6-deoxy-β-cyclodextrin (ENCD), were prepared by the saturated solution method in water under the preparation conditions as follows: the ratio of daidzein/ACD was 3∶1 and the stirring time was 72 h (83% and 67% yields, respectively).The formation of two inclusion complexes was confirmed by x-ray diffractometry (XRD) and themogravimetric (TG) analysis.The inclusion stoichiometry of the inclusion complexes was 1∶1 from the Job plot and their complexation stability constants (KS) were 899.2 and 203.8 L/mol from fluorescence titration, respectively.After formation of inclusion complexes with NCD and ENCD, the water solubility of daidzein was dramatically raised from 8.31 μg/mL to 15.2 and 13.2 mg/mL at 25℃, increasing by 1800-fold and 1500-fold.

Objective To investigate the diagnostic value of serum Cystatin C for early detection of renal damage in patients with liver cirrhosis. Methods 24-h creatinine clearance (CCr), serum level of cystatin C (CysC) and serum creatinine were measured in 76 patients with cirrhosis and t-test,Pearson's correlation test and ROC curve were used to evaluate the diagnostic significance of Cys C.Results The increase in Cys C level was associated with a decrease of CCr in the patients. Both Cys C and SCr were inversely correlated with CCr ( CysC: r =- 0. 763, P ＜ 0. 001; SCr: r=-0. 571,P＜0.01). Meanwhile, the area under the ROC curve was significantly higher in Cys C than in SCr (0. 830 vs. 0. 612). Conclusion Cystatin C is a more accurate and sensitive marker of renal diagnosis in liver cirrhosis. Detection of Cys C level in cirrhotic patients is of great significance for the prevention of liver-kidney syndrome.
