Solcoseryl improves learning and memory in rats.

Abstract

Our previous experiments have shown that Solcoseryl (S), a protein-free extract of calves' blood stimulates locomotor activity and decreases haloperidol catalepsy in rats. In this study the influence of S on acquisition, consolidation, and recall of both, conditioned avoidance responses (CARs) and passive avoidance behaviour was tested. S at the intraperitoneal (i.p.) dose of 1.25 ml/kg significantly improved acquisition and at the dose of 1.0 ml/kg recall of CARs. In the passive avoidance situation the significant effect on acquisition and recall of information was observed after i.p. injection of 1.0 ml/kg of S, and on consolidation after 0.75 ml/kg. These data indicate that S may positively affect the CNS processes responsible for learning and memory.

[Blocking the gastrin/cholecystokinin-B receptor autocrine loop influences the growth and apoptosis of human gastric cancer cells].

OBJECTIVE: To study whether gastrin/cholecystokinin-B (CCK-B) receptor autocrine loop exists in human gastric cancer cells and the effects of gastrin/CCK-B receptor autocrine loop on the growth and apoptosis of human gastric cancer cells. METHODS: Human gastric cancer cells of the line SGC-7901 were cultured. The expression of gastrin and CCK-B was detected by RT-PCR, immunocytochemistry and radioimmunoassay. Antibody against gastrin was added so as to block the autocrine loop to observe the growth rate, cell cycle and apoptosis by 3-(4.5-dimethylthiazol-z-yl) -2, 5-diphenyl tertrazolium blue (MMT) colorimetric assay and flow cytometry (FCM). RESULTS: The SGC-7901 cells co-expressed gastrin and CCK-B receptor mRNAs, confirmed by sequencing, thus forming gastrin/the CCK-B receptor autocrine loop. After the blocking of the autocrine loop by antibody against gastrin, the cell growth rate and the number of cells residing in the S-phase of the cell cycle decreased and the apoptotic rate increased in an antibody concentration-dependent manner. CONCLUSION: Human gastric cancer SGC-7901 cells possess the gastrin/the CCK-B receptor autocrine loop. Blocking the autocrine loop inhibits the cell proliferation and promotes the cell apoptosis.

[Proliferation inhibiting and apoptosis inducing effects of parthenolide on human multiple myeloma cells].

OBJECTIVE: To investigate the effect of parthenolide (PTL) on human multiple myeloma (MM) cells in vitro and its mechanism. METHODS: Human MM cells of the line PRMI8266 were cultured and treated with PTL of the concentrations of 1, 2.5, 5, 7.5, and 10 micromol/L for 24, 48, or 72 hours. MM cells treated with DMSO were used as control group. The optical density was measured so as to draw a growth curve. The cell viability was detected by MTT and trypan-blue exclusion. The apoptosis was detected by flow cytometry. AO/EB staining and Wright-Giemsa staining were used to observe the morphological changes of the cells by fluorescence microscope and light microscope respectively. The caspase-3 activity was evaluated by BD ApoAlert Caspase Colorimetric Assay Kit. RESULTS: PTL significantly inhibited the proliferation and viability of the MM cells time and dose-dependently (all P < 0.01), and significantly induced the cell apoptosis after 48 h in a dose-dependent manner (P < 0.01). The early cell apoptosis rates for PTL of the concentrations of 2, 5 and 10 micromol/L were 17.1% +/- 2.6%, 33.6% +/- 3.8%, and 40.9% +/- 3.1% respectively, all significantly higher than that of the control group (5.6% +/- 1.2%, all P < 0.01). The MM cells treated with PTL of the concentration of 5 micromol/L for 48 h showed typical cell apoptotic features. The caspase-3 activity of the MM cells was enhanced significantly by PTL in a time and dose-dependent manner (all P < 0.01). CONCLUSION: This first report of anti-proliferation and apoptosis induction effects of PTL on MM cells shows that able to significantly inhibit the proliferation and induce the apoptosis of MM cells and enhance the caspase-3 activity, PTL may be a potentially useful drug for treatment of MM.

[Experimental study on porcine keratinocytes cultured and purified rapidly and cocultured on acellular amnion in vitro].

OBJECTIVE: To explore an effective method to culture and purify porcine keratinocytes, to observe the morphological characteristics of porcine keratinocytes growing on acellular amnion and to offer the experimental basis for that the amnion is used for tissue engineering. METHODS: The primary porcine keratinocytes were cultivated with DKSFM (Defined keratinocyte-SFM) containing 10% fetal bovine serum (FBS). The second passage porcine keratinocytes were cultivated with the medium of DKSFM containing different concentrations of FBS. Because of the speciality that keratinocytes stick to flask fast, we purified the keratinocytes by 0.02% EDTA and 0.05% trypsin step by step. The second passage keratinocytes were seeded on amnion, the keratinocytes/amnion composites were observed by dye directly, histopathology and immunohistochemical staining. RESULTS: The proliferation of the primary porcine keratinocytes cultured with the medium of DKSFM containing 10% FBS was fast and the morphological characteristics were good. The cultivated porcine keratinocytes expanded to 60%-70% of the total area of the bottle of the flask after 5 days. The proliferation of the second passage porcine keratinocytes cultivated with the medium that DKSFM containing 5% FBS was faster than the second porcine keratinocytes cultured with the medium of DKSFM containing 10% FBS, or DKSFM without FBS. The proliferation of the second passage porcine keratinocytes cultivated with DKSFM without FBS was the slowest one among the 3 medium. The porcine keratinocytes that were purified by 0.02% EDTA and 0.05% trypsin step by step were got with high pure. After the keratinocytes were cultivated on the surface of amnion 12 days, the keratinocytes form a single layer on the surface of amnion and the cells were polygon and arranged like slab- stone. After 14 and 16 days, the cells contacted more closely. But at 16 days after the cells were seeded, some of the cells got aging. CONCLUSION: To culture primary porcine keratinocytes with the medium that DKSFM containing 10% FBS and to cultivate the second passage with the medium containing 5% FBS, the proliferation of porcine keratinocytes are faster. The method that purify the porcine keratinocytes is effective. Acellular amnion offers excellent bioscaffold to support keratinocytes to adhere and grow. After the porcine keratinocytes are cultivated on the surface of the acellular amnion 12 days, the morphologic characteristics are better than that of other groups.
