Protective Effect of Chlorella vulgaris and Spirulina platensis against ThioacetamideInduced Hepatorenal Toxicity in Male Rats
Summary
This paper is not directly about microplastics — it evaluates whether the microalgae Chlorella vulgaris and Spirulina platensis can protect against liver and kidney toxicity caused by thioacetamide in rats, finding significant protective effects via antioxidant mechanisms.
The present inquiry evaluated the possible pharmacological effects of Chlorella vulgaris(CV) and Spirulina platensis (SP) with special reference to their hepatorenal protectiveeffect as well as their antioxidant activities against thioacetamide (TAA) acute toxicity.Thirty-six male Wister albino rats, weighing from 100 to 120 gm were applied in thepresent study. Rats were randomly allocated into 6groups each of 6 animals. Group I wasmaintained as the control healthy group. It was administrated distilled water orally for onemonth and normal saline at a dose of 1 ml IP. On the last two days of the experiment. Theother groups were allocated into 5 groups including A, B, C, D and E. Group A was used as acontrol intoxicated with thioacetamide at a dose of 300 mg/ kg b.wt. IP for two days with24 hrs intervals before the end of the experiment. Group B was stated as a standardprotected group and it was treated with silymarin at a dose of 100 mg/kg b.wt. orally forone month. Group C was given Chlorella vulgaris orally at a quantity of 400 mg/kg b.wt.daily, for one month. Group D was given Spirulina platensis at a dose of 400 mg /kg b.wt.Orally daily for one month. Group E was given CV &SP at doses of 400 mg /kg b.wt eachorally daily for one month. Groups B, C, D, and E were intoxicated with thioacetamide(TAA), at an amount of 300mg/kg b.wt. IP for two days with 24 hrs intervals at the end ofthe month. Toxicity of rats with thioacetamide substantially elevated the levels of alaninetransferase and aspartate aminotransferase, serum urea, creatinine, and uric acid inaddition to increased malon-di-aldehyde concentration. However, it significantly decreasedtotal proteins, and total antioxidant capacity concentrations and decreased bloodparameters. As well as it induced histopathological alterations in hepatic and renal tissuedesigns (delete). On the other hand, oral administration of Chlorella vulgaris and Spirulinaplatensis ameliorated TAA-induced biochemical, pathological, and histopathologicalchanges in hepatic tissues and renal tissues. This study stated that these algae attenuatethioacetamide and protect against hepatorenal toxicity, via their antioxidant properties.

Concentration dependent toxicity of microplastics to marine microalgae
Researchers exposed the marine microalga Chlorella sp. to polystyrene microplastics at concentrations of 10 and 50 mg/L, finding that even low concentrations inhibited growth and disrupted photosynthesis, while higher concentrations caused more pronounced oxidative stress.
Evaluating physiological responses of microalgae towards environmentally coexisting microplastics: A meta-analysis
A meta-analysis of 52 studies found that microplastics inhibit microalgal growth and photosynthesis and induce oxidative damage, though microalgae can recover over time. Cyanobacteria are more vulnerable than green algae, and the relative size of microplastics to algal cells governs the mechanism of impact, while aged versus pristine microplastics have opposite effects on extracellular polymeric substance and microcystin production.
The Impact of Microalgae and Their Bioactive Compounds on Liver Well-being in Rats Subjected to Synthetic Phenolic Antioxidants
This review examines how microalgae and their bioactive compounds — including polysaccharides, pigments, and polyphenols — protect liver health in animal models, summarizing evidence for anti-inflammatory and antioxidant mechanisms. The authors note that algal-derived compounds show hepatoprotective effects in rodent studies, though human clinical evidence remains limited.
Ecotoxicological impact of virgin and environmental microplastics leachate on Chlorella vulgaris: Synergistic microbial-pollutant drivers cripple photosynthesis
Researchers compared the toxic effects of leachate from new versus environmentally weathered microplastics on a common green algae species. They found that weathered microplastics were up to 3.4 times more toxic, severely disrupting photosynthesis and introducing hundreds of bacterial species and pollutants that compounded the damage. The findings highlight that microplastics become significantly more dangerous as they age in the environment.
Recent progress on the toxic effects of microplastics on Chlorella sp. in aquatic environments
This review summarizes research on how microplastics affect Chlorella, a type of green algae that forms the base of aquatic food chains. Microplastics can slow algae growth, cause oxidative stress, and disrupt photosynthesis, which matters for human health because damage to these foundational organisms can ripple up through the food web and affect the quality of water and seafood.
