Abstract
Background: Portal hypertension (PH) can be measured indirectly through a hepatic vein
pressure gradient greater than 5 mmHg. Cirrhosis is the leading cause for PH
and can present as complications ascites, hepatic dysfunction, renal
dysfunction, and esophagogastric varices, characterizing gastropathy. Aim: To evaluate the use of carvedilol as primary prophylaxis in the development
of collateral circulation in rats submitted to the partial portal vein
ligament (PPVL) model. Method: This is a combined qualitative and quantitative experimental study in which
32 Wistar rats were divided into four groups (8 animals in each): group I -
cirrhosis + carvedilol (PPVL + C); group II - cirrhosis + vehicle (PPVL);
group III - control + carvedilol (SO-sham-operated + C); group IV - control
+ vehicle (SO-sham-operated). After seven days of the surgical procedure
(PPVL or sham), carvedilol (10 mg/kg) or vehicle (1 mL normal saline) were
administered to the respective groups daily for seven days. Results: The histological analysis showed no hepatic alteration in any group and a
decrease in edema and vasodilatation in the PPVL + C group. The laboratory
evaluation of liver function did not show a statistically significant change
between the groups. Conclusion: Carvedilol was shown to have a positive effect on gastric varices without
significant adverse effects.

Abstract
Background: Tools such as MELD score and DRI are currently used to predict risks and benefits on liver allocation for transplantation. Aim: To evaluate the relation between donor quality and recipient severity on liver allocation. Methods: Liver transplants performed in 2017 and 2018 were evaluated. Data were collected from Paraná’s State Government Registry. DRI was evaluated in relation to recipient MELD score and position on waiting list. Results: It was observed relation between DRI and position on waiting list: higher risk organs were allocated to recipients with worse waiting list position. There was no relation between DRI and MELD score. Afrodescendents and elderly donor organs were allocated to lower MELD score and worse waiting list position recipients. Conclusion: There is no relation between DRI and MELD on liver allocation. However, DRI interferes with allocation decision based on recipients waiting list position. Donor race and age interfere on both recipient MELD score and waiting list position

Rat liver and kidney post-mitochondrial dysfunction by addition of chronic mixed metal intoxication and hepatorenal wellness mediated by phenolic components from Croton zambiscus leaves. ENVIRONMENTAL TOXICOLOGY AND PHARMACOLOGY 2020; 74:103293. [PMID: 31760208 DOI: 10.1016/j.etap.2019.103293] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/13/2018] [Revised: 10/26/2019] [Accepted: 10/28/2019] [Indexed: 06/10/2023]
Abstract
Chronic exposure of mixed-metal intoxication has been associated with prolonged oxidative stress and severe hepatorenal damage. This present study demonstrates the hepatoprotective and renoprotective activity of Croton zambesicus (C-ZAMB) leaves, naturally occurring phenolic compounds against chronic mixed-metal (EOMABRSL) induced toxicity. 0.5 ml of EOMABRSL via oral route induced chronic hepatoxicity and nephrotoxicity on exposure for 98 days (non-withdrawal) and 70 days (withdrawal) by abnormal alteration in the levels of endogenous antioxidants. Moreover, EOMABRSL induced hepatorenal damage by increasing the markers of liver toxicity (ALT, AST, ALP, GGT and bilirubin) and kidney failure (creatinine, urea, uric acid, and renal electrolytes-Na+ and K+). Both non-withdrawal and withdrawal approaches of EOMABRSL-exposed animals exhibited hepatorenal dysfunctions by increasing the activity of eco-51-nucleotidase (51ENT) followed by the decreased in the activity of lactate dehydrogenase (LDH)-index of cellular ATP. These results were further supported by the histopathological examination of nephritic cells, hepatocytes and splenocytes, manifested by hepatocellular necrosis, swelling or degeneration of tubular kidney epithelial cells as well as coalescing splenic periarteriolar lymphoid sheaths (PALSs) and lymphoid haemosiderin. The chronic EOMABRSL intoxication was ameliorated by administration of phenolic antioxidants from C-ZAMB leaves. Therefore, our study supports the view that phenolic C-ZAMB leaves may mediate hepatorenal wellness on chronic exposure to mixed-metal intoxication.
