4.Relationship between muscarinic receptor subtypes and detrusor hyperreflexia in spinal cord transected rat
Chinese Journal of Urology 2001;0(08):-
Objective To investigate the relationship between muscarinic receptor subtypes and detrusor hyperreflexia. Methods Spinal cord was transected in male Wistar rats at L 1~2 level, changes of urodynamics were monitored 3 weeks later by cystometric studies.Spontaneous contraction frequency and strength of detrusor strip mustarded by carbachol (muscarinic receptor agonist), atropine (nonselective M antagonist), methoctramin (M 2 receptor selected antagonist) and 4 DAMP (M 3 receptor selected antagonist) were measured. Results Bladders after SCI showed littler capacity, lower compliance and hyperreflexia. Detrusor of all groups contracted at a definite tension. The contraction frequency in the hyperreflexia group (4.797?0.257 times/min) was higher than in the control's(3.227?0.173 times/min).There were no obvious changes while detrusor strips were mustarded by different muscarinic receptor antagonists.Carbachol could increase detrusor contraction frequency( 6.316 ?0.409 times/min) and the effect could be blocked by atropine(5.304?0.095 times/min) and 4 DAMP(5.046?0.089 times/min). Conclusions Detrusor is a rythmatic tissue at a difinite tension.Excitability rise of detrusor is the main cause of hyperrefexia. M 3 receptor can enhance the excitability of detrusor causing direct contraction.The function of M 2 receptor is still unclear.

Objective To evaluate clinical significance of detrusor leak point pressure (DLPP) in the damage of the upper urinary tract secondary to neurogenic voiding dysfunction. Methods 38 cases of voiding dysfunction received the urodynamic test,especially detecting of detrusor leak point pressure. Results 38 cases were divided into 2 groups by DLPP of 4.0 kPa,26 in high DLPP group and 12 in low DLPP group.The bladder capacity of the high pressure group is (422.95?183.27)ml,significantly less than the low pressure group (464.83?106.43)ml,and its compliance is lower as well as with DSD.Clinical results of B ultrasound,IVU,BUN,Cr show that the high pressure group has more serious than that in the low pressure group. Conclusions DLPP is valuable in evaluating the damage of upper urinary tract secondary to neurogenic voiding dysfunction.

AIM: To investigate whether the Acrysof Natural has the protective function for retina from blue light in morphology.METHODS: Fresh porcine eye cups were formed in vitro. Blue light beam between 420-450nm spectrum eradiated the porcine retina and cultured RPE cells in 30J/cm2 and 40J/cm2, respectively. The adjacent region in 3mm diameter was eradiated in various ways: exposed directly to light, through AcrySof one piece IOL, PMMA IOL,AcrySof Natural IOL, and without light. Then the eye cups were cultured for 48h. Lastly, tissue and cell structure were observed with light microscope and transmission electron microscope (TEM).RESULTS: In the retinal region without light, the structure of every layer was clear, cells in neuroepithelial layer arrayed in rule, some bubble presented in external granular layer and internal granular layer, RPE cells were compact, and the color of pigment article was coincident. In the region with direct blue light and that with 30J/cm2+Acrysof one-piece/ pMMlA, cells on photoreceptor and external granular layer were lost partially, bubble increased, RPE cells were with different sizes, and cell edema, cell lost and pigment article cluster could be seen.. In region with 30J/cm2+Natural, a little disorganization could be seen comparing to that without light, but more normal than those with Acrysof and direct eradia tion. When the power was 40J/cm2, the situation was similar to that with 30J/cm2 but more severe.CONCLUSION: ① the blue light intensity in 30J/cm2 and 40J/cm2 could both induce the acute retinal light injury, ② AcrySof one piece IOL and other PMMA IOLhave no obvious effect no retina comparing to direct eradiation, ③AcrySof Natural can weaken the injury of blue light to some extent.

Objective To explore the roles and possible mechanism of calcium-sensing receptor(CaSR) in cell cardiac hypertrophy model using angiotensin Ⅱ (Ang Ⅱ ).Methods The cultured neonatal rat ventricular myocytes were treated with Ang Ⅱ as cell cardiac hypertrophy model.Hypertrophic neonatal rat cardiomyocytes were treated with GdCl3(a specific agonist of CaSR) and/or with Ro318220(a specific inhibitor of PKC pathway).To evaluate the status of cardiac hypertrophy,cell diameter was observed by HE dyeing,and protein content was determined through coomassie brilliant blue protein kit.The intracellular calcium concentration( [ Ca2+]i) was determined by laser scanning confocal microscope.The protein expression of CaSR and PKC pathway were analyzed using Western blotting.Results ①Compared to the control group(0.1263 ± 0.0443),the protein expression of CaSR was increased in Ang Ⅱ group and in GdCl3 group(0.1963 ± 0.0375,0.2778 ± 0.0564,all P< 0.05).Moreover,compared with Ang Ⅱ alone,the increase was significant in GdCl3 group(P < 0.05).②Compared to control group(222.70 ± 22.09),AngⅡ group(392.16 ± 36.85) remarkably increased [Ca2+]i(P< 0.05),and this increase of [Ca2+]i was further enhanced in GdCl3 group (502.60 ± 44.21) versus Ang Ⅱ group (P < 0.05).③Compared to control group,Ang Ⅱ could induce cardiomyocyte hypertrophy,and GdCl3 enhanced the effect.Moreover,this enhancement was attenuated by Ro318220.④Compared to control group(0.27 ± 0.07,0.69 ± 0.06,0.87 ± 0.04),the protein expression of PKCα,PKCε and PKCδ was increased in Ang Ⅱ group(0.60 ± 0.16,1.02 ± 0.13,1.20 ± 0.18,all P< 0.05) and the protein expression of PKCα,PKCε was increased in GdCl3 group(0.82 ± 0.16,1.34 ± 0.12,all P < 0.05).Moreover,compared with Ang Ⅱ group,the protein expression of PKCα,PKCε was obviously increased in GdCl3 group (all P < 0.05);compared with GdCl3 group,the protein expression of PKCα,PKCε(0.41 ± 0.10,0.85 ± 0.14) was obviously decreased in Ro318220 group(all P < 0.05).Conclusions CaSR is involved in cardiac hypertrophy induced by Ang Ⅱ through PKC pathway in cultured neonatal rat cardiomyocytes.
