Chinese Journal of Obstetrics and Gynecology 2008;43(3):185-188
Objective To investigate the metabolism of lipid,calcium and phosphorus in women with endometriosis.Methods Clinical data of 223 patients with endometriosis and 200 patients without endometriosis were retrospectively analyzed.Electrochemiluminoimmunoassay was used to detect the levels of serum luteinizing hormone(LH),follicle-stimulating hormone(FSH),testosterone(T),estradiol(E2)and progesterone(P),and photoelectric colorimetry was used to determine the concentrations of serum triglyceride ( TG), total cholesterol ( TC ), low density lipoprotein ( LDL), high density lipoprotein (HDL), calcium and phosphorus in the patients with and without endometriosis. Results The levels of serum P were 2. 0 nmol/L and 1.8 nmol/L in endometriosis patients with age≤35 years old (case group A)and >35 years old (case group B), and 1.6 nmol/L and 1.2 nmol/L in patients without endometriosis at age≤35 years old (control group A) and > 35 years old (control group B), respectively. A significant difference was found between case group A and control group A, and between case group B and control group B. The levels of serum LH was significantly higher in case group B (7. 2 U/L) than that in control group B (6. 1 U/L), however, there was no significant difference between case group A (7. 0 U/L) and control group A (6. 5 U/L). Also no significant difference in serum FSH, T and E2 levels was found between case group A (respectively, 6.2 U/L,1.1 nmol/L and 269 pmol/L) and control group A (respectively, 6.3 U/L, 1.1nmol/L and 264 pmol/L), also between case group B (respectively, 6.6 U/L, 1.0 nmol/L and 345pmol/L) and control group B (6. 6 IU/L, 0. 9 nmol/L and 279 pmol/L). The concentrations of serum TG in case group A and B (0. 71 mmol/L and 0. 72 mmol/L) were significantly lower than in control group A and B (0. 92 mmol/L and 1.08 mmol/L), respectively. The concentrations of serum LDL in case group A and B [ (2. 2 ± 0. 5) mmol/L and (2.4 ± 0. 6) mmol/L]were also significantly lower than in control group A and B[ (2. 4 ± 0. 7) mmol/L and (2. 62 ±0. 63) mmol/L], respectively. However, the concentrations of serum HDL in case group A and B [ (1.62 ± 0. 31) mmol/L and(1.53 ± 0. 32) mmol/L] were significantly higher than in control group A and B [ ( 1.48 ± 0. 21 ) mmol/L and ( 1.37 ± 0.22) mmol/L], respectively.In addition, the concentrations of serum TC were not significantly different between case group A and control group A [ (4. 2 ± 0. 7) mmol/L and (4. 29 ± 0. 71 ) mmol/L], and between case group B and control group B [ (4. 4±0. 8) mmol/L and (4. 5±0. 7) mmol/L]. The levels of serum phosphorus in case group A and B [ (1.01 ± 0. 22) mmol/L and (0. 89 ± 0. 18 ) mmol/L] were significantly lower than in control group A and B [ ( 1.23 ± 0. 24) mmol/L and ( 1.10 ±0. 13 ) mmol/L ] , respectively. But the levels of serum calcium had no significant difference between case group A and control group A [ (2. 39 ± 0. 23 ) mmol/and (2.41 ± 0. 12) mmol/L], and between case group B and control group B [(2.40 ± 0.28) mmol/L and (2. 42 ±0. 20) mmol/L]. Conclusion The abnormal metabolism of lipid and phosphorus, and the higher levels of serum P may playing a role in the pathogenesis of endometriosis.

Objective To explore the relationship between learning and memory ability and antioxidant enzyme (SOD, CAT, GSH-Px)activities in specific brain areas of D-galactose model rats. Methods The aging models were induced by D-galactose in 3-month old rats, and the learning and memory ability of aging model was detected in model MG-2 maze. The activity of SOD, CAT and GSH-Px in brain cortex, cerebellum,hippocampus, striatum and hypothalamus were detected immediately after rats were executed. Results The learning and memory ability of D-ga-lactose aging model was lower than that of control group. The difference of antioxidant enzyme activity among different rat brain areas was significant. The correct response rate of D-galactose aging model was( 58.9 ± 5.4 ) %, which is significantly lower than that of the control group (66.8 ±8.9) %, P < 0.05. The times of response required reaching the standard after 24h of aging model rats was significantly higher than that of the control( Aging group :29.5 ± 12.8, Control group 16.6 ± 6.2; P< 0.01 ). Correct response rate after 24h was significantly lower than that of the control ( Aging group :67.3 ± 10.3 , Control group: 79.1 ± 6.9; P< 0.01 ). The SOD activity in cortex, hippocampus and striatum( Aging group :66.12 ±5.89,80.46 ± 6.57,87.82 ± 6.87; Control group :57.63 ± 4.21,67.46 ± 6.80,68.37 ± 6.52) significantly reduced ( P < 0.05 and P < 0.01 ).The CAT activity in cortex, hippocampus, striatum and hypothalamus( Aging group :6.45 ± 0.55,5.86 ±0.35,6.93 ± 0.63,8.89 ± 0.38; Control group :5.32 ± 0.56,4.76 ± 0.38,4.37 ± 043,6.11 ± 0.37) significantly reduced ( P < 0.05 and P < 0.01 ). GSH-Px activity was similar in each brain area without significance ( P > 0.05 ). Conclusions The learning and memory ability of aging mode rats decreased. The change of antioxidant enzyme activities in hippocampus, cortex, striatum and hypothalamus is closely related to learning and memory ability.
