Instability of misoprostol tablets stored outside the blister: a potential serious concern for clinical outcome in medical abortion.
2014
IntroductionMisoprostol (Cytotec) is recognised to be effective for many gynaecological indications including termination of pregnancy, management of miscarriage and postpartum haemorrhage. Although not licensed for such indications, it has been used for these purposes by millions of women throughout the world. Misoprostol tablets are most often packaged as multiple tablets within an aluminium strip, each within an individual alveolus. When an alveolus is opened, tablets will be exposed to atmospheric conditions.ObjectiveTo compare the pharmaco technical characteristics (weight, friability), water content, misoprostol content and decomposition product content (type A misoprostol, type B mis…
Toxocara canis infection induces antigen-specific IL-10 and IFNγ production in pregnant dogs and their puppies
2005
Toxocara canis (T. canis) is originally a parasite of canine bitches and their pups. The pathogenicity of T. canis infection is enhanced during pregnancy and puppyhood. The aim of this study was to investigate if modification of IFNgamma and IL-10 secretion occurs during infection in pregnant dogs and puppies. Analysis of cytokines secreted could let us hypothesize a role for IL-10 and/or IFNgamma in T. canis infection. We tested T. canis-specific production of IFNgamma and IL-10 by lymphocytes of pregnant dogs and their puppies after in vitro re-exposure to purified excretory/secretory antigen (ESAg) from T. canis. Blood mononuclear cells (BMC) isolated from pregnant dogs and their puppies…
Cytokine components and mucosal immunity in the oviduct of Xenopus laevis (amphibia, pipidae)
2011
Abstract Most studies on the mucosal immunity in female reproductive tissues have been performed in mammals. In all species, apart from their reproductive strategies, immunity in the genital mucosa is required to defend the host against luminal pathogens. In this study we investigated the role of the innate immunity of the oviductal mucosa of Xenopus laevis , an amphibian characterized by external fertilization. In particular we examined the expression and localization of Interleukin-1β (IL1B), Macrophage migration inhibitory factor (MIF) and Interleukin-1 receptor type 1 (IL1R1) in different oviductal portions including an upper glandular region, an intermediate and a lower aglandular regi…
Single and Synergistic Effects of Type 2 Cytokines on Eosinophils and Asthma Hallmarks
2020
Abstract The type 2 cytokines IL-5, IL-13, and IL-4 play an important role in the induction and progression of asthma. According to the Global Initiative for Asthma guidelines, blood eosinophil numbers are one marker that helps to guide treatment decisions in patients suffering from severe forms of asthma. Effects of type 2 cytokines were analyzed, alone or in combination, on eosinophils in blood and other compartments and on the development of asthma symptoms. C57BL/6 mice received a single intranasal application of equimolar amounts of IL-5, IL-13, and IL-4, alone or in combination. Numbers, activation state, and migratory behavior of eosinophils in bone marrow (BM), blood, lung, and bron…
Nitric oxide and sensory afferent neurones modulate the protective effects of low-dose endotoxin on rat gastric mucosal damage
1995
Pretreatment (1 h) with low doses (5-40 micrograms/kg i.p.) of Escherichia coli endotoxin dose dependently reduced the gastric mucosal damage induced by a 10 min challenge with 1 ml ethanol (50% and 100%) in conscious rats. Treatment with the nitric oxide synthesis inhibitor, NG-nitro-L-arginine methyl ester (L-NAME, 5 and 10 mg/kg i.p.), significantly inhibited the protective effects of endotoxin (40 micrograms/kg i.p.). The actions of L-NAME were reversed by the prior administration of L-arginine (100 mg/kg i.p.). The protective effects of endotoxin were not influenced by pretreatment with dexamethasone (5 mg/kg s.c. twice) or indomethacin (5 mg/kg s.c.). However, ablation of sensory affe…
Regulation of cytochrome P450 IID by acute phase mediators in C3H/HeJ mice.
1992
Abstract Cytochrome P450 IID6 is a drug metabolizing enzyme and the major target antigen in LKM-1 antibody positive chronic active hepatitis. The histological hallmark of chronic active hepatitis is a lymphocytic infiltrate in the liver. It is unknown whether and how cytokines produced and secreted by these tissue infiltrating mononuclear cells regulate the cellular expression of cytochrome P450 IID6. To study the effect of interleukin 1, tumor necrosis factor and interleukin 6 on the hepatocellular RNA expression of cytochrome P450 IID, we injected each of the cytokines in C3H HeJ mice. We found a time-dependent suppression of the cytochrome in the liver. Six hours after the intraperitonea…
Ex vivoevidence for PGE2and LTB4involvement in cutaneous leishmaniasis: relation with infection status and cytokine production
1996
SUMMARYEx vivoculture of spleen cells from BALB/c mice infected with 2 × 106Leishmania major(L.major) promastigotes were cultured with ConcanavalinA (ConA) or leishmanial antigen (L. Ag) and tested for prostaglandin E2(PGE2) and for leukotriene B4(LTB4), in order to study their involvement in the evolution of cutaneous leishmaniasis and the connexion with lymphokine-mediated responses. The data were compared with those obtained in BALB/c mice protected againstL. majorby sublethal irradiation (550 rad; cured mice). In the unprotected BALB/c mice the levels of PGE2that were responsible for the depression of interferon-γ (IFN-γ) and tumour necrosis factor-α (TNFα) Th1-associated cytokines and …
Guillain-Barré syndrome after orthotopic liver transplantation: A clinical manifestation of immune reconstitution inflammatory syndrome?
2018
Guillain-Barrè Syndrome, as part of the spectrum of dysimmune neuropathies, is unexpected to occur in immunocompromised hosts. We describe a clinical case of Guillain-Barrè syndrome, occurred a few weeks after a liver transplant, and we postulate that our case would satisfy all requirements to explain this peripheral nervous system complication as a clinical manifestation of an Immune reconstitution inflammatory syndrome. In this setting of liver transplantation, complicated by potentially multiple infective triggers, reduction of immunosuppression and reversal of pathogen-induced immunosuppression, through antimicrobial therapy, may have led to pro-inflammatory response. The pro-inflammato…
Long term complications following pelvic and para-aortic lymphadenectomy for endometrial cancer, incidence and potential risk factors: a single insti…
2019
ObjectiveTo determine the incidence of long term lymphadenectomy complications in primary surgery for endometrial cancer and to elucidate risk factors for these complications.MethodsA retrospective chart review was carried out for all patients with endometrial cancer managed at Parma University Hospital Unit of Gynecology and Obstetrics between 2010 and 2016. Inclusion criteria were surgical procedure including hysterectomy and lymphadenectomy (pelvic or pelvic and aortic). We identified patients with postoperative lymphocele and lower extremity lymphedema. Logistic regression analysis was used to identify predictive factors for postoperative complications.ResultsOf the 249 patients tested,…
Intrarectal immunization with rotavirus 2/6 virus-like particles induces an antirotavirus immune response localized in the intestinal mucosa and prot…
2006
ABSTRACTRotavirus (RV) is the main etiological agent of severe gastroenteritis in infants, and vaccination seems the most effective way to control the disease. Recombinant rotavirus-like particles composed of the viral protein 6 (VP6) and VP2 (2/6-VLPs) have been reported to induce protective immunity in mice when administered by the intranasal (i.n.) route. In this study, we show that administration of 2/6-VLPs by the intrarectal (i.r.) route together with either cholera toxin (CT) or a CpG-containing oligodeoxynucleotide as the adjuvant protects adult mice against RV infection. Moreover, when CT is used, RV shedding in animals immunized by the i.r. route is even reduced in comparison with…
