Abstract
Experimental data were provided to demonstrate the inhibitory effects of retinoids (retinal, retinoic acid, retinyl acetate and retinyl palmitate) and carotenoids (beta-carotene, lycopene and crocetin) on the growth and development of the C-6 glioma cells inoculated in rats. In the pretreatment experiments, most of these compounds could prolong the latency period of T50 (time for 50% tumor incidence). At week 7, the growth inhibition was 57-67% (P less than 0.02) with carotenoids and 40-55% (P less than 0.05) with retinoids. In the post-treatment experiments, the growth inhibition was 30-55% (P less than 0.05) with carotenoids and 21-42% (P less than 0.05) with retinoids. No significant hepatotoxic effect was observed in all treated groups as indicated by the constant levels of serum enzymes (e.g. aspartate amino-transferase, alanine amino-transferase and alkaline phosphatase) and bilirubin. The mechanisms of tumor inhibition through the enhancement of anti-tumor immunity by both carotenoids and retinoids were discussed.

Abstract
Forty-five patients with hydronephrosis due to pelviureteric junction stricture were operated on at Kaohsiung Medical College Hospital between 1971 and 1986. In unilateral cases, the left kidney was affected more frequently than the right (24 to 13), while 8 (18%) had bilateral ureteropelvic stricture. Of the 45 cases, 24 cases (53%) underwent Anderson-Hynes pyeloplasty, 5 cases underwent Y-V plasty, 5 cases underwent ureterolysis and 11 cases underwent simple nephrectomy due to severe hydronephrosis. Except for the 11 nephrectomy cases, 11 of the remaining 34 cases had ureteral catheter placement and 9 cases had double-J ureteral catheter placement, postoperatively; another 14 cases received no ureteral stent for draining urine. The results were very encouraging with clinical improvement in 64% of the patients, and improvement in the pelviocaliceal system and early appearance of contrast medium in the ureter in 47% of the patients. The results of pyeloplasty with and without a nephrostomy or ureteral stent were compared. Patients with a nephrostomy or ureteral stent tended to have an increased incidence of urinary tract infections and longer hospital stays. In general, the results of treatment were poorer for patients with a nephrostomy or ureteral stent, than for patients without.

Abstract
This paper reports the result of the tumor in site induced by several nickel compounds in mice. Three nickel compounds (Ni3S2, NiCl, pure nickel powder) were injected separately to the right arm pit subcutaneously (5 mg/mouse). At the end of the 62nd week, the tested mice were sacrificed. Only nickel sulfide induced tumors in the site of injection, the incidence of tumor was 36%. The majority of the tumors were fibrosarcomas, only 2 rhabdomyosarcomas. The tumors might infiltrate into the surrounding tissues, a few metastasized to the liver and/or the lungs.

Abstract
The inhibitory effects of 4 retinoids, namely, retinal (Ral), retinoic acid (RA), retinyl acetate (RAc), and retinyl palmitate (RP), and 3 carotenoid including beta-carotene (BCT), lycopene (LCP), and crocetin (CCT) on the growth and DNA synthesis of rat C-6 glioma cells were studied. All the retinoids and carotenoids caused reduction of plating efficiency and inhibition of the cellular growth. RA was the most potent inhibitor of plating efficiency, followed in decreasing order by RAc, Ral, LCP, RP, BCT, and CCT. The effects of various doses of retinoids and carotenoids on the inhibition of DNA synthesis were clearly demonstrated in the growing C-6 glioma cells, whereas negligible effects of these compounds on the RNA and protein synthesis were observed. These results suggested that retinoids or carotenoids are biologically active as anti-tumor agents against brain tumor cells in culture, while carotenoids appeared to be less active.

Abstract
A review of 20 polycystic kidney disease patients in admitted to Kaohsiung Medical College Hospital is herein reported. In this series 60% of the patients were in the fourth to sixth decades of life at the time of diagnosis. The average age was 50 years. The disease was generally more commonly found in the females than in male subjects. Flank pain and gross hematuria was the most common presenting symptom in these cases. In 70% of the patients hypertension were noted, besides 55% of patients have associated liver cysts and 9% of the patients have associated pancreatic cystic diseases. In a comparison of ultrasonography, CT scans, renal angiography, intravenous pyelography and retrograde pyelography in the evaluation of polycystic kidney disease, it was found that CT scans and ultrasonography had more than a 90 per cent diagnostic accuracy rate, while intravenous pyelography had only a 30 percent accuracy rate. Because of improved treatments such as antibiotic and hemodialysis techniques the five-year survival rate of patients, with polycystic kidney diseases, may be increased.

Abstract
The records of 53 patients treated for urethral stricture at Kaohsiung Medical College Hospital over a 8-year period were reviewed. Young men those affected and trauma appeared to have been the most frequent etiological cause. Of the 53 patients 12 were treated by filiform dilatation , 33 were treated by metal sound dilatation , and 8 underwent a pull-through technique. Good results were noted in 29 cases (54.7%), fair in 10 (18.9%) and poor results in 14 (26.4%). When the results were analyzed according to the method of treatment, poor results were most common among those who had underwent the pull-through technique and the metal sound dilatation as compared to filiform dilation group.

Abstract
Cases analysis of 24 operations for the anterior urethral injuries is presented. 7 patients were treated one-stage transperineal end-to-end anastomosis and 17 underwent an immediate urethral realignment over a fenestrated catheter. Hospital stays were generally short and the rate of complication was low as well as the number of blood transfusions needed in both groups. The operating time however was longer in patients in the anastomosis group. Postoperatively, urethral strictures occurred in 71% of the patients who underwent one-stage transperineal end-to-end anastomosis and in 65% of those treated by realignment over a fenestrated catheter. The high incidence of postoperative stricture formation caused both techniques indicated neither procedure as a valuable modality for the primary and early treatment of anterior urethral injuries. According to the authors the suprapubic cystostomy and delayed urethroplasty offer a better choice of therapy.

Abstract
Detomidine is a potent non-narcotic sedative agent which is currently in the process of being approved for veterinary clinical use in the United States. Since no effective screening method in horses is available for detomidine, we have developed an 125I radioimmunoassay for detomidine in equine blood and urine as part of a panel of tests for illegal drugs in performance horses. Our 125I radioimmunoassay has an I-50 for detomidine of approximately 2 ng/ml. Our assay shows limited cross-reactivity with the pharmacodynamically similar xylazine, but does not cross-react with acepromazine, epinephrine, haloperidol or promazine. The plasma kinetic data from clinical (greater than or equal to 5 mg/horse) as well as sub-clinical doses indicate first-order elimination in a dose-dependent manner. Within the first 30 minutes after intravenous (IV) administration of 30 mg/horse, plasma levels peak at approximately 20 ng/ml and then decline with an apparent plasma half-life of 25 minutes. Diuresis can occur with administration of clinical doses of detomidine and this effect was accounted for in the analysis of urine samples. Using this method, administration of 30 mg/horse can be readily detected in equine urine for up to 8 hours after IV injection. Additionally, doses as low as 0.5 mg/horse can be detected for short periods of time in blood and urine with use of this assay. Utilization of this assay by research scientists and forensic analysts will allow for the establishment of proper guidelines and controls regarding detomidine administration to performance horses and assurance of compliance with these guidelines.

Abstract
A one step enzyme-linked immunosorbent assay (ELISA) and a particle concentration fluorescent immunoassay (PCFIA) test for furosemide were evaluated as part of a panel of pre- and post-race tests for illegal medication of racing horses. These tests are very sensitive to furosemide with an I-50 for furosemide of about 20 ng/ml. The test is also rapid; an average pre-race complement of 10 samples can be analyzed in 90 minutes or less. The ELISA test results can be read with an inexpensive spectrophotometer, or even by eye. Both the PCFIA test and the ELISA test readily detect the presence of furosemide in equine blood for up to five hours after administration of the recommended therapeutic dose of this agent. The principal utility of these tests lies in rapid screening of samples for compliance with regulations governing the use of furosemide. Thus these tests can be used pre-race to determine whether horsemen have treated their horses with furosemide, and post-race to perform an initial evaluation of whether certain blood concentrations of furosemide have been exceeded. Pilot trials with these systems in Kentucky and Illinois suggest that these tests are economical and effective, and can form part of an analytical approach to substitute for the detention barn system of monitoring furosemide administration.

Abstract
51Cr-labelled leucocyte adherence inhibition (LAI) assay was used as an index to study the activity of xenogenic immune RNA (iRNA) in inducing normal LACA mouse spleen lymphocytes to mediate tumor specific response in vitro. RNA was extracted from the spleen and lymph nodes of the guinea pigs immunized by S180 or H22 ascitic tumor cells and from those of the normal guinea pigs. Extracts of S180 or H22 tumor cells and that of normal LACA mouse livers were prepared by PBS method respectively. Three kinds of RNA and three kinds of cell (tissue) extracts were grouped into nine combinations. A defined number of 51Cr-labelled lymphocytes was added to each group. The results showed that only in the combination of two kinds of iRNA and the corresponding tumor cell extract, adherence of normal lymphocyte was significantly inhibited. Serum from tumor bearing host inhibited LAI reaction mediated by iRNA. The "blocking" effect was specific since it occurred only when the serum and tumor extract in the reaction system were taken from the same tumor-bearing donor.

Abstract
Chemopreventive agents are compounds that inhibit carcinogenesis when administered prior or subsequent to a course of carcinogen administration. The effects of dietary administration of crocin dyes on the hepatic damage induced by aflatoxin B1 (AFB1) and dimethylnitrosamine (DMN) in rats were investigated. Female Sprague-Dawley rats were treated with different dosages of AFB1 (0.9 or 4.5 mg/kg) or DMN (8 or 20 mg/kg) by i.p. administration, and the different degrees of hepatic damage were revealed by the elevations of levels of serum marker enzymes such as aspartate amino-transferase, alanine aminotransferase, alkaline phosphatase, gamma-glutamyl transpeptidase and lactic dehydrogenase. Pre-treatment of the animals with crocin dyes 50 mg/kg daily for three consecutive days, the enzyme elevations were significantly suppressed. This suggested that the crocin dyes possessed chemopreventive effects on the early acute hepatic damage induced by AFB1 or DMN. Feeding experiments demonstrated that crocin dyes at 0.1% in the diet could suppress partially the chronic hepatic damage induced by multiple dosages of AFB1 or DMN, but at a higher concentration of 1% crocin dye failed to do so because of their host toxicity. Crocin dyes are extracted from the fruits of Gardenia jasminoides and consist of carotenoids and geniposides as active principles. The protective mechanisms of crocin dyes may be attributed to their carotenoids which are converted metabolically to retinoids in rats.

Abstract
Crocin dyes, isolated from Gardenia jasminodes, did not affect hepatic function when they were orally administered to rats in a daily dose of 50 mg/kg for 8 days, but could induce acute hepatic discoloration. A high dosage of 100 mg/kg for 2 weeks could induce both hepatic damage and black pigmentation, but a lower dose of 100 mg/kg for 40 days did not. Rats fed on diet containing 1% of crocin dyes for four months were shown to have mild hepatic functional disorders and pigmentation. The black pigmentation of the liver and the acute hepatic damage associated with the discoloration were completely reversible. During the period of hepatic pigmentation caused by high dose of crocin dyes, the urine had abnormally increased porphyrin excretion and tended to display a blackish green color. The skin also appeared purplish black. The mechanism of black pigmentation seemed to correlate with the gradual accumulation of crocin dyes. In summary, the crocin dyes have a very low toxicity in rats even in high experimental dosage which would hardly happen in human practice. It is therefore suggested that the crocin dyes are safe for coloring foods.

Abstract
A fully automated system for performing fluorescence polarization immunoassay has been developed. Reagents for each assay are contained in coded reagent packs, and no reagent reconstitution is required. A common buffer is used for all assays, minimizing changeover and set-up times for each assay. A single sample may be assayed in 5 min, or 20 samples in 10 min. A single-tube blank subtraction for each sample results in highly precise polarization values and obviates sample interferences. We have used this method for assays of gentamicin, theophylline, phenytoin, and phenobarbital. CVs are 1-4%, and the results correlate well with those by other methods. Because of the instrument design and the stability of the reagents, daily calibration is not required; samples may therefore be run immediately upon receipt or batched as desired.

We have used this method for assays of gentamicin, theophylline, phenytoin, and phenobarbital. CVs are 1-4%, and the results correlate well with those by other methods. Because of the instrument design and the stability of the reagents, daily calibration is not required; samples may therefore be run immediately upon receipt or batched as desired.

Abstract
New alpha-thiohemiaminals, 7alpha-phenylthio-7-epideoxynupharidin-6-ol, the diasteriomeric 7beta-phenylthiodeoxy-nupharidin-6-ol, and 3-methyl-3-methylthio-4-hydroxyquinolizidine, were prepared and reduced to the corresponding beta-tert-amino sulfides. The configuration at C-7 of the beta-tert-amino sulfides was determined by observing the direction of the solvent-induced shift of the C-7 methyl proton resonance. The configuration at C-7 of the new alpha-thiohemiaminals was established by correlations with the beta-tert-amino sulfides and confirmed, in the case of the deoxynupharidine derivatives, by circular dichroism and ascertaining the sterochemistry of deuteride incorporation upon sodium borodeuteride reduction of the alpha-thiohemiaminal. The in vitro antifungal activities of six compounds possessing the quinolizidine skeleton, including all the newly synthesized compounds as well as some previously reported ones, and amphotericin B were tested against several human pathogenic fungi. Besides amphotericin B, only the two deoxynupharidine alpha-thiohemiaminals were active, especially against Histoplasma capsulatum and Blastomyces dermatitidis. The observations indicate activity is derived from the 3-furyl group and the functionality from which alpha-thioimmonium ions can be produced.

Abstract
The morphological characteristics of pathogenic and saprophytic strains of Torula jeanselmei (Fungi Imperfecti) are indistinguishable. Some basic physiological properties of T. jeanselmei were investigated in the hope of separating the human pathogenic strain from common saprophytes in a clinical laboratory. Nitrogen and carbon assimilation tests were not useful for distinguishing the pathogen, since all strains, pathogenic and saprophytic, were able to assimilate nitrogen from ammonium, nitrate, and nitrite sources, and all were able to utilize glucose, fructose, galactose, cellobiose, lactose, glycerol, and starch. It appeared that temperature range for growth might be useful in the identification of the pathogen. All pathogenic strains grew well at 37 C but poorly at 10 C; in contrast, all saprophytes could grow at 10 C but were unable to grow at 37 C (with two exceptions).
