Between disease-free endometria and those of patients with endometriosis, adenomyosis, and or leiomyomas Kitawaki et al., 1999b, 2000b ; , whereas the incidence and abundance of OB-RL mRNA expression are comparable among diseased and disease-free endometria Kitawaki et al., 2000a ; . These findings are supportive of the view that oestrogens are not a direct factor regulating the OB-RL expression. In contrast with the proliferative endometrium, the abundance of OB-RL mRNA expression in the secretory endometrium was decreased by ~50%. The decrease was reproduced by progesterone exposure to the proliferative endometrium but not to the secretory endometrium. This suggests that OB-RL mRNA in the secretory endometrium had been fully suppressed by progesterone. The organ culture technique has been previously validated; using the same method, we have shown progestin induction of 17-hydroxysteroid dehydrogenase type 2 Kitawaki et al., 2000b ; . The results suggest that the decrease in the OB-RL expression is mainly due to progesterone that is secreted from corpus luteum. Moreover, the present study showed that the progesterone suppressed the OB-RL mRNA to a similar extent in both epithelial and stromal cells, indicating that the decrease was not caused by a change in conformation ratio of epithelial and stromal cells in the secretory phase. Under our conditions, the progesterone suppression of OB-RL mRNA was obtained more efficiently by the monolayer culture technique ~80% ; than by the organ culture technique ~50% ; . We consider that the discrepancy might be caused by the difference of experimental conditions. Although at the transcriptional level, progesterone suppression. The kinetic model is shown in Fig. 2 and equations are described under Experimental Procedures. VmaxW and VmaxQ are the maximum velocities for the 10-hydroxylation of R-warfarin and 3-hydroxylation of quinidine, respectively; KS1 is the dissociation constant for E ES1 and KS2 for E ES2; and are the factors by which KS1 or KS2 ; , k1, and k2 are influenced upon binding of a second substrate to the enzyme. Data are presented as mean standard error.

Cystitis This is commonly taken to mean pain on passing urine. It actually means an inflammation of the bladder. People usually refer to cystitis when they think that they have an infection and mean frequency, urgency and dysuria. detrusor muscle The muscle in the bladder wall that contracts during voiding. dysuria Abnormal voiding, which may be painful or difficult. enuresis Bedwetting, normally known as nocturnal enuresis, because it occurs at night. frequency Having to pass urine more commonly than normal normal is up to seven times a day ; or more often than every two hours. hesitancy A period of delay while waiting with the sensation of wanting to void before voiding begins. micturition See voiding. nocturia Having to get up at night, more than once, after falling asleep, to pass urine. This is unusual in a normal person under the age of around 60. After this age it is normal to need to pass urine about once more for every decade over 60, that is, a 70 year old would be expected to pass urine twice at night and an 80 year old three times. perineum The area between the vagina and the anus. prolapse The displacement of part of the body from its normal position. The term is usually used in association with changes of the pelvic organs `prolapsing' into the vagina. strangury The sensation of wanting to pass urine but being unable to do so. stress incontinence The leakage of urine on raised intra-abdominal pressure leakage with coughing, sneezing or exercise ; . ultrasound A test used to look at the body using sound waves to build up a picture. ureter The tube connecting the kidney to the bladder. urethra The tube connecting the bladder to the outside.
Levamisole responses are sensitive to Ca2 + 10 mol l1 10 mol l1 10 mol l1 10 mol l1 ACh ACh ACh An effect of CaM kinase II in modulating ACh levamisole receptors implies that the response will also be sensitive to Ca2 + . We tested the effect of levamisole at different concentrations in preparations bathed for longer than 30 min in lowCa2 + APF and in normal Ca2 + APF. Elimination of Ca2 + from the bathing solution is known to 10 mol l1 Control 20 min wash 10 min wash reduce cytoplasmic Ca2 + concentrations because KN-93 low-Ca2 + extracellular solutions reduce the 10 mV opening of Ca-activated Cl-channels Thorn and Martin, 1987 ; .
