Behavioural effects on dopaminergic transmission of a phenylindane derivative, Lu 19-005 [(+/-)-trans-3-(3,4-dichlorophenyl)-N-methyl-l-indanamine,
HCI
], with potent inhibitory effect on dopamine (DA), noradrenaline (NA) and serotonin (5-HT) uptake in rats and the effect on DA, NA and 5-HT activity in mice have been studied and compared with those of other known DA, NA and 5-HT uptake inhibitors with different selectivity ratios. Lu 19-005 induced stereotyped behaviour after parenteral and oral administration with a duration of action of more than 24 h. The stereotyped licking and biting induced by Lu 19-005 was antagonized by reserpine and cis(Z)-flupentixol, but not affected by prazosin, p-chlorophenylalanine and alpha-methyl-p-tyrosine pretreatments. Metergoline slightly facilitated the onset of stereotypy. Lower doses of Lu 19-005 induced ipsilateral circling in unilaterally 6-hydroxy-DA-lesioned rats. Finally, Lu 19-005 antagonized the catalepsy induced by perphenazine. In mice, Lu 19-005 potentiated the apomorphine-induced gnawing, reversed tetrabenazine-induced
ptosis
and potentiated the behavioural effects of 5-HTP within a similar dose range. The effects of Lu 19-005 were compared with those of other reference compounds. Nomifensine had qualitatively similar effects in rats although of much shorter duration. In mice, nomifensine selectively reversed tetrabenazine-induced
ptosis
. Weaker effects in all test models were found with bupropion, LR 5182 and GBR 13.069, compounds with inhibitory effect on DA and NA uptake. The DA-, NA- and 5-HT-uptake inhibitor diclofensine, however, had no effect in rats except in the 6-hydroxy-DA-circling test and had low potency in mice. The specific 5-HT- and NA-uptake inhibitors citalopram and talsupram, respectively, were ineffective in all rat models.(ABSTRACT TRUNCATED AT 250 WORDS)

The aim of this study was to investigate quantitative mRNA expression of matrix metalloproteinases MMP-1, MMP-2, MMP-9, and their inhibitors, the tissue inhibitors of metalloproteinases
TIMP-1
, TIMP-2 and TIMP-3, in vaginal wall tissue from women with stress urinary incontinence compared to continent controls. Vaginal wall tissues were obtained from 7 women with stress urinary incontinence/severe pelvic
prolapse
and 15 continent controls. RNA was then extracted and quantified. Quantitative competitive reverse transcription (QC-RT-PCR) was carried out with oligonucleotide primers to quantify MMP-1, MMP-2, MMP-9,
TIMP-1
, TIMP-2 and TIMP-3 mRNA expression. Stress continent women demonstrated a significant decrease in
TIMP-1
and mRNA expression (P = 0.03). There was no difference in TIMP-2, TIMP-3, MMP-2 or MMP-9 mRNA expression between stress incontinent women and controls. However, MMP-1 mRNA expression was significantly increased (P = 0.05) in the incontinent group and the MMP-1/
TIMP-1
ratio (P = 0.04) was consistent with increased collagen degradation in the stress incontinence. Stress incontinent women demonstrated an increase in MMP-1 mRNA expression and a decrease in the inhibitor
TIMP-1
mRNA expression. Both these findings are consistent with increased collagen breakdown as a pathologic etiology of incontinence.

Gynecological literature pertaining to
prolapse
or stress urinary incontinence published over the past four decades was reviewed to determine whether signs of herniosis, the systemic connective tissue co-morbidity known to play a significant role in abdominal herniation, were present and differed from controls. A total of eight indications were reported: (1) Genetic factors, i.e., family history and race, were predictive. (2) An increase in the incidence was observed in association with heritable diseases of collagen and their formes frustes (e.g., joint laxity). (3) Recurrence rate after repair was high (30%). (4) Fragmentation and degeneration of smooth muscle and collagen fibers were observed histologically. (5) Biochemistry demonstrated a decline of 24-40% in collagen content of skin, round ligament, cardinal ligament, periurethral vaginal wall, cervix, pubocervical, cervicococcygeal, and vesicovaginal fasciae. (6) In patients with stress urinary incontinence, collagen content decreased 60%. This change was independent of age, parity, menopausal status, and weight. (7) Matrix metalloproteinase (MMP-2 and MMP-9) activity increased fourfold and that of their inhibitor
TIMP-1
decreased. (8) Cigarette smoking, an acquired factor, increased the incidence of stress urinary incontinence. This commonality with the etiology of abdominal herniae explains why gynecologists have decreased their emphasis on childbirth injury and, like herniologists, have moved to discard the dogma "prolapse" as a designate for extraperitoneal herniation in the pelvis.

Pelvic organ
prolapse
(
POP
) is a common disorder that can disturb the health and quality of life of females. However, the basic pathophysiology and underlying mechanism of
POP
are not fully understood. Matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) have been reported to be associated with the onset and development of
POP
. In the present study, to characterize the differential expression profile of MMPs and TIMPs in female patients with and without
POP
, a total of 72
POP
patients were sampled as a patient group and 72 non-
POP
patients that underwent hysterectomy due to benign tumors were sampled as a control group. Immunohistochemistry and polymerase chain reaction analysis were used to detect the expression levels of MMP-1, -2, -3 and -9 as well as
TIMP-1
protein and mRNA in the anterior vaginal wall tissues. The expression levels of MMP-1, -2, -3 and -9 in the patient group were found to be significantly higher than those in the control group. By contrast,
TIMP-1
expression levels in the patient group were significantly lower than those in the control group. Correlational analysis revealed a significantly positive correlation among the expression levels of MMP-2, -3 and -9.
TIMP-1
expression levels were significantly negatively correlated with the expression levels of MMP-3 and -9. In addition, the expression levels of MMP-1 exhibited a positive correlation with those of MMP-2, -3 and -9, but a negative correlation with those of
TIMP-1
. The results demonstrated that the increased expression levels of MMPs and the reduced expression levels of TIMPs were directly associated with the presence of uterine
prolapse
, indicating that the differential expression levels of MMPs and TIMPs were correlated with the occurrence and development of
POP
. This data may assist in elucidating the molecular mechanism of MMP and TIMP involvement in
POP
, and also provide an underlying theoretical basis for the prevention and treatment of
POP
.
