    Opis:
    It is very difficult to cure pregnant females suffering from infections, because of the risk which might occur during treatment by several, even herbal, medications. Many of these substances, among them extracts from plants, have antimicrobial, anti-inflammatory and immunostimulatory properties owing to their polyphenols content, but also may reveal unwanted effects on the fetal development because of their anti-angiogenic properties. The aim of the present study was to elucidate whether daily feeding pregnant and nursing mice 0.2 mg/kg epigallocatechin (EGC), previously recognized as angiogenesis inhibitor, may lead to abnormalities in morphology of spleen and in some parameters of immune function of their adult, 6-week old progeny. Morphometry of EGC offspring spleens revealed lower number of lymphatic nodules and their larger diameter than those found in the control offspring. Cellularity of spleens was lower in EGC offspring than in the controls. Cytometric analysis showed that this decline concerns lymphocytes with CD335 (p<0.001), CD19 (p<0.01) and CD4 (p<0.05) markers. No differences were observed in the humoral response to the immunization with SRBC, and in the proliferative response of splenocytes to mitogens PHA, ConA and LPS.

    Opis:
    Lymphocyte-induced angiogenesis test (LIA) is a model of local graft-versus-host (GVH) reaction, marker of the earliest events resulting from activation of donor lymphocytes after contact with host semi-allogeneic histocompatibility antigens. The effect of in vivo oral administration of Aloe vera gel for 21 days to maternal strain (Balb/c) donor mice on the ability of their splenic lymphocytes to induce cutaneous angiogenesis (LIA test) in F1 Balb/c x C3H recipients, was studied. Results: Neovascular reaction evaluated 72 hours after cells grafting was significantly lower in F1 mice grafted with lymphocytes collected from Aloe- fed donors, than in recipients of lymphocytes collected from respective controls. Conclusions: This observation opens the promise of safe and ethically acceptable possibility of use of Aloe vera gel in human donors in prevention of GVHD in recipients of bone marrow grafts.

    Opis:
    Cranberries and cranberry-derived diet supplements are often recommended for the treatment of urinary tract infections, also during pregnancy. These products contain strongly anti-angiogenic chemical compounds which could not be indifferent to the developing fetus. In the present work we evaluated the effect of feeding pregnant and lactating mice American cranberry extract (daily dose 0.88 mg) on the morphology and some parameters of spleen and kidney function of their adult progeny. Six weeks after delivery the morphometry of spleen and kidney, cytometric analysis of spleen lymphocytes, evaluation of humoral response to SRBC (Sheep Red Blood Cells), and examination of serum creatinine/urea concentration, were performed in the offspring. Spleens of progeny from experimental (E) group differed from the spleens of progeny of control mice in the lower number of lymphatic nodules and their larger diameter. Cytometry of spleen cells from progeny of E mothers revealed more CD19⁺ and CD8⁺ lymphocytes than in the control group. No difference was seen in the response to immunization by red blood cells of sheep (SRBC) between control and E offspring. An increase in the diameter of glomeruli was observed in the kidneys of the experimental group in comparison with the control group. No abnormalities in creatinine and urea serum level were observed. A higher concentration of VEGF and bFGF in E offspring sera in comparison to the controls was seen. Conclusion: Although the observed differences between the control and experimental group were not large, caution is recommended in using cranberries and their extracts during pregnancy until more research will be done on this topic.

    Opis:
    The genus Rhodiola (Crassulaceae) consists of many species, growing mainly in Asia and traditionally used as adaptogens and anti-inflammatory drugs. In order to elaborate herbal immunostimulator which could be safely given to pregnant women, we performed a study on immunotropic effects of feeding pregnant and lactating mice Rhodiola kirilowii extracts. This paper presents the results of the first part of our study – spleen content of selected polyphenols, spleen cellularity, splenocytes phenotype and their response to mitogens. Experiments were performed on adult inbred females of Balb/c strain, mated with adult males. Females, since copulatory plug was noted, up to the 28-th day after delivery were fed daily with 20 mg/kg b.m. water (RKW) or hydro- lcoholic (RKW-A) extracts of Rhodiola kirilowii. Results: 1. Significantly lower proportion of pregnant mice in experimental groups than in the control. 2. Cellularity of spleen and flavonol quercetin spleen concentration were significantly lower in experimental groups in comparison to the controls. 3. Flavanols ( (+)-catechin and epicatechin) levels were significantly higher in the spleens of experimental mice than in the controls. 4. Positive correlation between spleen cellularity and quercetin, and negative correlation between spleen cellularity and epicatechin content were observed. 5. Spleen mass and spleen lymphocytes phenotype and proliferation in RKW and RKW-A fed mice did not differ from the control. These results, together with suspicion of some embryo- oxicity, are worrying and eliminate the possibility of use Rhodiola kirilowii extracts for long-term treatment in pregnant females.
