An endogeous defensive concept, renewed cytoprotection/adaptive cytoprotection: intra(per)-oral/intragastric strong alcohol in rat. Involvement of pentadecapeptide BPC 157 and nitric oxide system

With intra(per)-oral strong alcohol application at the tongue, swallowed, we renewed Robert's stomach cytoprotection/adaptive cytoprotection concept. We assessed strong (96%) alcohol-induced severe or minute lesions in stomach, tongue-esophagus-stomach-duodenum lesions, and sphincter pressure (lower esophageal and pyloric) upon administration intragastrically (at 1 h) or intra(per)-orally at the tongue, and swallowed (at 1, 5, 15, 30 min; and 1, 2, 24 h). The assessment also included combined administrations (intra(per)-oral at the tongue, swallowed and intragastric (at 1 h)). Immediate post-alcohol intraperitoneal medication (mg/kg) was the stable gastric pentadecapeptide BPC 157 (0.01, 0.00001; a Robert's cytoprotection mediator; with a therapeutic effect), NOS-blocker L-NAME (5), and NOS-substrate L-arginine (100 mg), (NO-system involvement). After intragastric strong alcohol administration, severe stomach ulcerations appeared along with widespread tongue, esophagus, duodenum redness, and minimal sphincter pressures. By contrast, a particular syndrome (immediate overlapping of cytoprotection/adaptive cytoprotection) (minute gastric lesion or largely attenuated hemorrhagic ulceration, tongue affected, minute esophageal and duodenal lesions, but with intact mucosa; sphincters pressures lowered) appeared after intra(per)-oral administration (1 min-24 h) as well as after combined administrations (intra(per)-oral + intragastric). BPC 157 apparently cured all alcohol-lesions, amplified the spontaneously initiated strong mucosal beneficial effect, rescued sphincter pressures; NO-agents (L-arginine (slight mucosal amelioration) and L-NAME (aggravation)) showed NO-system involvement, but no comparable effects on dropped sphincters pressures. In conclusion, minute gastric lesions (with oral application of strong alcohol at the tongue and swallowed, without, or with intragastric application of strong alcohol) renew and revise Robert's stomach cytoprotection/adaptive cytoprotection concept. The tongue becomes a new initial target, resulting in spontaneous reversal of strong alcohol-stomach lesions. BPC 157 therapy functions also within the redirected complexity of Robert's stomach cytoprotection/adaptive cytoprotection concept.

Esophagogastric anastomosis in rats: Improved healing by BPC 157 and L-arginine, aggravated by L-NAME

AIM

To cure typically life-threatening esophagogastric anastomosis in rats, lacking anastomosis healing and sphincter function rescue, in particular.

METHODS

Because we assume esophagogastric fistulas represent a particular NO-system disability, we attempt to identify the benefits of anti-ulcer stable gastric pentadecapeptide BPC 157, which was in trials for ulcerative colitis and currently for multiple sclerosis, in rats with esophagocutaneous fistulas. Previously, BPC 157 therapies have promoted the healing of intestinal anastomosis and fistulas, and esophagitis and gastric lesions, along with rescued sphincter function. Additionally, BPC 157 particularly interacts with the NO-system. In the 4 d after esophagogastric anastomosis creation, rats received medication (/kg intraperitoneally once daily: BPC 157 (10 μg, 10 ng), L-NAME (5 mg), or L-arginine (100 mg) alone and/or combined or BPC 157 (10 μg, 10 ng) in drinking water). For rats underwent esophagogastric anastomosis, daily assessment included progressive stomach damage (sum of the longest diameters, mm), esophagitis (scored 0-5), weak anastomosis (mL H₂O before leak), low pressure in esophagus at anastomosis and in the pyloric sphincter (cm H₂O), progressive weight loss (g) and mortality. Immediate effect assessed blood vessels disappearance (scored 0-5) at the stomach surface immediately after anastomosis creation.

RESULTS

BPC 157 (all regimens) fully counteracted the perilous disease course from the very beginning (i.e., with the BPC 157 bath, blood vessels remained present at the gastric surface after anastomosis creation) and eliminated mortality. Additionally, BPC 157 treatment in combination with L-NAME nullified any effect of L-NAME that otherwise intensified the regular course. Consistently, with worsening (with L-NAME administration) and amelioration (with L-arginine), either L-arginine amelioration prevails (attenuated esophageal and gastric lesions) or they counteract each other (L-NAME + L-arginine); with the addition of BPC 157 (L-NAME + L-arginine + BPC 157), there was a marked beneficial effect. BPC 157 treatment for esophagogastric anastomosis, along with NOS-blocker L-NAME and/or NOS substrate L-arginine, demonstrated an innate NO-system disability (as observed with L-arginine effectiveness). BPC 157 distinctively affected corresponding events: worsening (obtained with L-NAME administration that was counteracted); or amelioration (L-arginine + BPC 157-rats correspond to BPC 157-rats).

CONCLUSION

Innate NO-system disability for esophagogastric anastomoses, including L-NAME-worsening, suggests that these effects could be corrected by L-arginine and almost completely eliminated by BPC 157 therapy.

Ovarian vein thrombosis--a case report

OBJECTIVE AND IMPORTANCE

Ovarian vein thrombosis is a rare condition usually seen in the puerperium. The incidence is 0.05-0.18% of pregnancies. Possible complications of ovarian vein thrombosis are sepsis, thrombus extension into the inferior vena cava or renal veins and pulmonary embolism.

CLINICAL PRESENTATION

A 31-year-old puerpera complained about abdominal pain in the right lower quadrant and right inguinal region.

INTERVENTION

Ultrasonographic examination and multislice computed tomography (MSCT) revealed the right ovarian vein thrombosis. Patient was treated with low-molecular weight heparin and antibiotics for 2  weeks. She was discharged with oral anticoagulants for 6  months.

CONCLUSION

Ovarian vein thrombosis should be taken under consideration in the post-partum period.

Third Stage of Labor and Acupuncture

Background: Acupuncture use in obstetrics has been increasing in Western medicine, especially to alleviate complications of pregnancy, the most important cause of maternal mortality worldwide. One quarter of maternal deaths are caused by complications in the third stage of labor, an interval between complete delivery of the baby and the complete expulsion of the placenta. Methods: This review analyzes the increased acupuncture use for pregnancy complications as a potential method of reducting maternal mortality during the third stage of labor. This overview focuses on acupuncture points and techniques to manage the third stage of labor and help patients with retained placentas. Passive (or expectant) management of the third stage of labor is occasionally associated with massive obstetric hemorrhage, a major cause of maternal morbidity and mortality, especially in low-income countries. Conclusions: Active management of the third stage of labor has been shown to reduce the risk of postpartum hemorrhage. Use of acupuncture in the first and second stages of labor could lead to a faster separation of the placenta in the third stage of labor. The possible effects of acupuncture in cases of retained placentas may have significant implications for possible complications and final outcomes of labor. Further studies are needed for more conclusive results.

Pentadecapeptide BPC 157 and the esophagocutaneous fistula healing therapy

Esophagocutaneous fistulas are a failure of the NO-system, due to NO-synthase blockage by the NOS-blocker L-NAME consequently counteracted by l-arginine and gastric pentadecapeptide BPC 157 (l-arginine <BPC 157), precipitating a therapeutic benefit. Previously, there was an established BPC 157-NO-system interaction. BPC 157 GEPPPGKPADDAGLV, MW 1419 (LD1 not achieved), is a safe and stable anti-ulcer peptide, successful in inflammatory bowel disease trials, counteracting esophagitis, sphincter failure, gastrointestinal and skin ulcers, gastrocutaneous or colocutaneous fistulas. We treated rats with established cervical esophagocutaneous fistulas throughout four days (both open skin and esophageal defects, with significant leakage) with BPC 157 (parenterally and perorally) and L-NAME (blocking NO genesis) and l-arginine (NO-substrate) alone or in combination. RT-PCR investigated eNOS, iNOS, COX-2 mRNA levels in the fistulas. We evidenced a closely inter-related process of unhealed skin, esophageal defects, unhealed fistulas (up regulated eNOS, iNOS and COX2 mRNA levels), usually lethal, particularly NO-system related and therapy dependent. Generally, the course of fistula healing was accelerated either to a greater extent (with BPC 157 (in particular, less eNOS gene expression) completely counteracting L-NAME effects, in L-NAME+BPC 157 and L-NAME+l-arginine+BPC 157 groups), or to a lesser extent (with l-arginine). Conversely, the process was aggravated, rapidly and prominently (with L-NAME). In particular, BPC 157 was effective either given per-orally/intraperitoneally, in μg- and ng-regimens. Shortly, defects started to heal, with less fistula leakage and no mortality at day 4. Failure of pyloric and lower esophageal sphincter pressure was restored, with practically no esophagitis.

Pentadecapeptide BPC 157 and its effects on a NSAID toxicity model: diclofenac-induced gastrointestinal, liver, and encephalopathy lesions

AIMS

We attempted to fully antagonize the extensive toxicity caused by NSAIDs (using diclofenac as a prototype).

MAIN METHODS

Herein, we used the stable gastric pentadecapeptide BPC 157 (GEPPPGKPADDAGLV, MW 1419), an anti-ulcer peptide shown to be efficient in inflammatory bowel disease clinical trials (PL 14736) and various wound treatments with no toxicity reported. This peptide was given to antagonize combined gastrointestinal, liver, and brain toxicity induced by diclofenac (12.5mg/kg intraperitoneally, once daily for 3 days) in rats.

KEY FINDINGS

Already considered a drug that can reverse the toxic side effects of NSAIDs, BPC 157 (10 μg/kg, 10 ng/kg) was strongly effective throughout the entire experiment when given (i) intraperitoneally immediately after diclofenac or (ii) per-orally in drinking water (0.16 μg/mL, 0.16 ng/mL). Without BPC 157 treatment, at 3h following the last diclofenac challenge, we encountered a complex deleterious circuit of diclofenac toxicity characterized by severe gastric, intestinal and liver lesions, increased bilirubin, aspartate transaminase (AST), alanine transaminase (ALT) serum values, increased liver weight, prolonged sedation/unconsciousness (after any diclofenac challenge) and finally hepatic encephalopathy (brain edema particularly located in the cerebral cortex and cerebellum, more in white than in gray matter, damaged red neurons, particularly in the cerebral cortex and cerebellar nuclei, Purkinje cells and less commonly in the hippocampal neurons).

SIGNIFICANCE

The very extensive antagonization of diclofenac toxicity achieved with BPC 157 (μg-/ng-regimen, intraperitoneally, per-orally) may encourage its further use as a therapy to counteract diclofenac- and other NSAID-induced toxicity.

Choroidal sclerosis in localized scleroderma (morphea en plaque)

Plaque morphea is a superficial type of morphea (localized scleroderma) which is characterized by various fibrotic areas of the dermis without systemic features. We present a 63-year-old man with morphea en plaque. The skin on his forearms and feet was taut, thickened and hidebound with scattered telangiectatic changes. Autoantibody profile was obtained and only ANA were positive (1:80). The patient had a decreased vision in the only functional, left eye. Our case is specific because the patient negated any kind of health problem, meaning the morphea and visual deterioration were of outstanding importance for him. Choroidal sclerosis and fundus appearance was extremely impressive and, to our knowledge, this is the first report of such unique case of ocular involvement in the literature.
