Twenty yearling lambs of Southeast Nigeria dwarf, liveweight ($18{\pm}1.9 kg$) were grouped into 5 treatments. Dry brewer's grain was substituted for maize offal in the experiment diets namely A to E at 0%, 15%, 30%, 45% and 60% respectively, as supplement to low quality, dry season cassava leaf top and Andropogan gayanus hay at 1:1 ratio that lasted for 56 days. After which 5 of the lambs (average bodyweight=$24.3{\pm}1.5kg$) were transferred to metabolism crates to determine the digestibility and nitrogen/protein balance studies. While the mean group intakes were (945.9, 996.1, 1,040.5, 1,148.5 and 1,037.7 g conc. DM/day), the growth rates were (115.1, 124.1, 152.5, 168.5 and 123.1 g liveweight gain/day), respectively. There was a recorded decline in both intake (p>0.05) and growth rate (p<0.05) as the level of dry brewer's grain was increased beyond 45% of the supplement. Similar trend was observed on the protein and organic matter efficiency ratios (p>0.05) together with the organic matter intake. The urine nitrogen output was also significant (p>0.05). The work further revealed that, at a certain critical level of intake, dry brewer's grain is able to support growth rates measurable to or better than those noted when feeding maize offal to lambs, and went on to prove dry brewer's grain as an attractive supplementary feed for the drier months of the year, in the Southeast of Nigeria.

Platinum coordination complexes are currently one of the most compounds used in the treatment of solid tumors. However, its use is limited by severe side effects such as renal toxicity. Our platinum-based drug discovery program is aimed at developing drugs capable of diminishing toxicity and improving antitumor activity. We synthesized new Pt (Ⅱ) complex analogue containing 1,2-diaminocyclohexane (dach) as carrier ligand and 1,2-bis(diphenylphosphino) ethane (DPPE) as a leaving group. Furthermore, nitrate was added to improve the solubility. A new series of [Pt(trans-ddach)(DPPE).$2NO_3(PC)$ was synthesized and characterized by their elemental analysis and by various spectroscopic techniques [infrared (IR), $^{13}carbon$ nuclear magnetic resonance (NMR)]. PC demonstrated acceptable antitumor activity aganist P388, L-1210 lymphocytic leukemia cells and SK=OV3 human ovarian adenocarcinoma cells, and significant. activity as compared with that. cisplatin. The toxicity of PC was found quite less than thar of cisplatin using MTT, $[^3H]$ thymidine uptake and glucose consumption tests in rabbit proximal tubule cells, human kidney cortical cells and human renal cortical tissues. Based on these results, this novel platinum compound represent a valuable lead in the development of a new anticancer chemotherapeutic agent capable of improving antitumor activity and low toxicity.

The present study was aimed to investigate the preventive effects of rebamipide on the multiple organ dysfunction in a rat model of circulatory shock induced by bacterial endotoxin (E. coli lipopolysaccharide; LPS) in comparison with that of methotrexate. Endotoxemia for 6 hours resulted in little change in the levels of hemoglobin and neutrophils. However, treatment with methotrexate decreased significantly the numbers of circulating neutrophils. Significant increases in serum alanine aminotransferase (ALT,958 $\pm$ 250 lU/L, p<0.001) and aspartate aminotransferase (AST, 1350 $\pm$ 295 lU/L, p<0.001) levels induced by endotoxemia were significantly decreased by rebamipide and methotrexate. The increased level of lactic acid dehydrogenase (LDH) by LPS (2850 $\pm$ 467 lU/L, p<0.05) was significantly inhibited by rebamipide, but not by methot.elate. The elevated serum creatinine (1.2$\pm$0.1, p.0.05) and urea levels (55.3$\pm$6.5 mg/dL, p.0.01) by LPS were also decreased by rebamipide, but not by methotrexate. In line with these results, the plasma concentration of tumor necrosis factor-$\alpha$ (TNF-7,167 $\pm$ 20 pg/mL) was significantly increased upon injection of endotoxin at 1 hour by 1570$\pm$100 pg/mL, and declined to 312$\pm$35 pg/mL at 6 hours. The TNF-$\alpha$ level at 6 hours was significantly decreased by rebamipide to 207$\pm$8 pg/mL (P<0.05). Taken together, it is summarized that rebamipide inhibits the development of multiple ogran dysfunction by inhibition of neutrophil activation in association with inhibition of TNF-$\alpha$ formation in a murine model of endotoxemia.

The crude ethanol extract of B. repanda showed the cytotoxic activity against Polio virus (25% activity at $150{\mu}g$/disk) and the minor cytotoxic activity against BSC cells (African green monkey kidney). However, the crude ethanol extract of B. repanda was non-toxic to murine leukaemia cells CCL 46 P388D1 ($IC_{50}$, > 62,500 ng/ml). Cytotoxic and antifungal activities were strongly shown by Fr. 64-3 which was eluted with 90% $CH_3CN/H_2O$, 100% $CH_3CN$, and 50% $CH_3CN/H_2O$(SM 2 at $150{\mu}g$/disk). The fraction 64-3 also showed the most cytotoxic activity against murine leukaemia cells (128 mg, $IC_{50}$ 10,051 ng/ml at $75{\mu}g$/disk). These results suggest that this fraction has a potent antifungal activity against the dermatophytic fungus Trichophyton mentagrophytes ATCC 28185.

Ten, heretofore unreported, $ 5^I-methyl-5^I-[2-(5-substituted uracil-1-yl)ethyl)]-2^I-oxo-3^I$-methylenetetrahydrofurans (H, F, Cl, Br, I, $ CH_3$,$CF_3$,$CH_2CH_3$,$ CH=CH2$, SePh) (7a-j) were synthesized and evaluated against four cell lines (K-562, FM-3A, P-388 and U-937). For the preparation of ${\alpha}$-methylene-${\gamma}$-butyrolactone-linked to 5-substituted uracils (7a-j), the convenient Reformasky type reaction was employed which involves the treatment of ethyl ${\alpha}$-(bromomethyl)acrylate and zinc with the respective 1-(5-substituted uracil-1-yl)-3-butanone (6a-j). The 5-substituted uracil ketones (6a-j) were directly obtained by the respective Michael type reaction of vinyl methyl ketone with the $K_2CO_3$(or NaH)-treated 5-substituted uracils (5a-j) in the presence of acetic acid in the DMF solvent. The .alpha.-methylene-.gamma.-butyrolactone compounds showing the most significant antitumor activity are 7e, 7f, 7h and 7j (inhibitory concentration $(IC_50)$ ranging from 0.69 to $2.9 {\mu}g/ml$), while 7b, 7g and 7i have shown moderate to significant activity. The compounds 7a, 7c and 7d were found to be inactive. The synthetic intermediate compounds 6a-j were also screened and found marginal to moderate activity where compounds 6b and 6g showed significant activity $(IC_50:0.4~2.8 {\mu}g/ml)$.

Purpose: To determine whether calcified carotid atherosclerotic plaques(CCAPs) and mineralized laryngeal cartilages (MLCs) were more frequently detected on digital or film-based panoramic radiographs. The clinical relevance of this question is that some radiopacities seen on digital radiographs may correspond to medium-density tissues that are not necessarily mineralized. Materials and Methods: Data were collected from panoramic radiographs and the respective reports issued by 2 private oral radiology centers. A total of 388 radiographs and reports were divided into film-based (group A) and digital (group D) radiographs. The frequencies of CCAPs and MLCs were analyzed using the Fisher exact test, and odds ratios were also calculated (${\alpha}=1%$). Results: The mean age of patients whose reports and radiographs showed CCAPs and/or MLCs ranged from 50.1 to 54.1 years. There was a predominance of females. A higher frequency of CCAPs and MLCs was observed in group D than in group A at both centers(P<0.01). CCAPs and MLCs were detected 4 times more frequently in group D than in group A at one of the centers. Conclusion: CCAPs and MLCs were more frequently detected on digital than on film-based panoramic radiographs. Further studies are needed to determine whether such radiopacities do indeed correspond to mineralized, rather than medium-density, tissues.

The surface properties (water sorption and repellency, adhesion) are closely related to the surface tension of polymer solids. The critical surface tension (${\gamma}_c$) and surface tension (${\gamma}_s$) of a polymer solid were estimated by the contact angle method by our quantitative imaging system. BPDA (3,3',4,4'-biphenyl tetracarboxylic dianhydride)-BAPP (1,3-Bis(4-aminophenoxy) propane) polyimide was successfully synthesized. The ${\gamma}_c$ values were analyzed by a Zisman plot, a Young-$Dupr\acute{e}$-Good-Girifalco plot, and a log ($1+cos{\theta}$) vs log ${\gamma}_L$ plot. The ${\gamma}_s$ value of BPDA-BAPE polyimide was evaluated using the geometric mean equation and our multiple regression analysis. The calculated values of ${{\gamma}_s^d$ (a dispersion component), ${{\gamma}_s^p$ (a polar component), ${{\gamma}_s^h$ (a hydrogen bonding component), and ${\gamma}_s$ were 30.79, 9.32, 0.20, and 40.31 $mN{\cdot}m^{-1}$, respectively. The ${\gamma}_s$ of BPDA-BAPP polyimide containing both a methylene group and an ether group was larger than that of the polyimide containing only a methylene group.

Purpose : We compared the pain reducing effect of orally administered glucose solution with EMLA cream and pacifiers during venipuncture in newborn infants. Methods : Fifty newborn infants(30 prematures) were enrolled in this study. We performed these four pain-reducing methods to all infants in serial order. Group A(control) did not receive any treatment; to group B, EMLA cream was applied on the skin for 1 hour; group C(or D) received 10 percent(or 30 percent) glucose solution orally; group E used pacifiers. Symptoms and signs associated with pain at venipuncture were measured with the Premature Infants Pain Profile(PIPP) scale. Results : There was no significant difference in the PIPP scores between preterm and fullterm infants. The mean PIPP scores of groups were A : $12.5{\pm}2.5$, B : $10.1{\pm}2.6$, C : $9.4{\pm}2.0$, D : $6.5{\pm}2.1$ and E : $8.7{\pm}2.3$; the mean scores of groups B, C, D and E were significantly lower than that of group A(all, P<0.001 except B(P<0.05)), and the mean score of D was significantly lower than those of B, C and E(P<0.001, P<0.005, P<0.05, respectively). The percentages of patients with PIPP scores above 6, which means pain, were A : 100 percent, B : 82 percent, C : 56 percent, D : 40 percent and E : 70 percent. The percentages of patients with PIPP scores above 12, which means severe pain, were A : 72 percent, B : 30 percent, C : 22 percent, D : 0 percent and E : 14 percent; that of group D was clearly lowest. Conclusion : These results support the use of oral glucose solution, EMLA, and pacifiers for pain reduction as effective intervention at venipuncture in newborn infants. The most effective method was a 30 percent oral glucose solution.
